Analisi agli Elementi Finiti Jobs

Hi I will share the details with the shortlisted candidates. Thanks

This tssk focuses on using finite element analysis (FEA) to study the mechanical behaviour of a sugar mill roller shaft under realistic operating conditions. The task requires modelling the shaft in engineering software (NX Nastran) to predict how it deforms and where stresses are concentrated, particularly at critical نقاط where failure is likely due to fatigue. Students must apply appropriate loads (such as roll pressure and torque), define constraints, and choose suitable mesh and element types while justifying all modelling decisions. The analysis is carried out for two scenarios—roll load only, and combined roll load with torque—to compare their effects on stress and deformation. Finally, the results, assumptions, and engineering reasoning must be clearly presented in a st...

I need a detailed modal analysis carried out in ANSYS Mechanical (Workbench or APDL) on a composite beam that is mounted on linear springs at both ends. The study is part of my master’s research, so every modelling choice—from element selection and mesh sensitivity to boundary condition justification—must be fully traceable. Two configurations must be investigated: 1. The bare beam on linear springs. 2. The same beam on linear springs with a centrally-mounted lumped mass (a disc). I already have the exact beam dimensions and material properties for the composite lay-up; I will share them once the project starts. What I require from you is to import or build the geometry, assign the composite stack, model the linear spring supports correctly, and extract natural frequ...

requires stress analysis on a reactor nozzle. They intend fitting a dip pipe through the nozzle, but need to know that the nozzle is suitable, and need to be sure the dip pipe can do the job, bearing in mind that the vessel is fitted with an agitator. Do you think this is something you can help with? In addition to the physical data the things I’d like you to consider are: Longest dippipe we could have without internal vessel modifications (to add supports etc..) Mechanical design for a directional dip-pipe to direct recirculation to the vessel wall , and if this is ok for stress/erosion risk on the vessel wall given the high recirculation flow rates Vessel fabrication drawings will be provided Nozzle will be used for the dip-pipe Vessel data sheet will be provided with process an...

I am in the detail-design phase of a new aircraft and need focused help finishing three intertwined tasks: CAD modeling of the airframe, disciplined material selection, and verification through structural analysis. The high-level geometry, aerodynamic data, and load cases are already defined; what remains is turning those inputs into production-ready 3D models and substantiating every spar, skin, and joint. Here is how the work will flow: • CAD modeling – Clean, parametric 3D models of the wing, fuselage, control surfaces, and primary subsystems, ready for downstream manufacturing drawings. Native files in SolidWorks, CATIA, or Siemens NX plus neutral STEP outputs are required. • Material selection – A trade study covering candidate alloys and composites, with just...

I need two separate yet comparable EnergyPlus models of a commercial building so I can study how a pair of alternative design strategies influence daylight and whole-building energy use. My focus on daylighting is two-fold: first, how deeply natural light penetrates the occupied zones; second, how each design mitigates daylight glare. On the energy side, I want a clear breakdown of impacts on the heating, cooling, lighting and ventilation loads. Here is the workflow I have in mind: you create (or adapt) the baseline geometry and envelope, duplicate it into an alternative design with the chosen façade or skylight strategy, then set up the daylighting controls, schedules and sensors. After running annual simulations, you will deliver the raw IDF files, output reports and a concise co...

I have a sheet-metal part that has to be built, validated, and reported entirely inside CATIA V5. I have the basic geometry sketched out, but I need an expert who can turn it into a clean, fully-parametric Sheet Metal Part, set up the right material properties, thickness parameters, bend tables, and reliefs, and then run the required simulation and analysis on the model to confirm it meets strength and deformation limits before manufacturing. Here is what I expect from you: • Re-create or refine the sheet-metal part in CATIA V5 Sheet Metal workbench, keeping design intent intact and all parameters editable. • Prepare an analysis set-up in the Generative Structural Analysis (or relevant) workbench: apply loads and boundary conditions that I will provide, mesh the part appropri...

I need a clean, well-documented static FEA study of a shift fork carried out entirely in Abaqus. The key outcome is a clear picture of the stress distribution throughout the component under its working load. You will receive the 3-D model and loading / boundary conditions; your task is to mesh, run the simulation, post-process the results and return: • The complete Abaqus input file set, ready to rerun. • Contour plots and images that highlight critical stress zones. • A concise report summarising methodology, mesh quality, material data, and numeric results, with brief engineering commentary. Please attach examples of past work that show similar static studies. If you also handle dynamic or thermal cases that is a plus, but for this assignment only the static st...

I need a complete engineering package for a 72" × 26' three-phase separator rated to 65 bar, dedicated to oil and gas separation. The vessel, piping, and skid must comply with ASME Section VIII Div 1 (2025) and all associated codes that apply to a high-pressure production environment. Licensed Software to be used such as PV Elite (Hexagon) or COMPRESS (CodeWare) or AutoPIPE Vessel (Bentley) Scope of work Please develop every aspect of the skid-mounted system—from process design through fabrication drawings—so that a shop can move directly into manufacturing once the package is approved. Because production schedules are tight, I’m looking for final, issue-for-construction documents as soon as possible. Required deliverables • Design calculation...

I will provide DXF drawings for several serpentine interconnect geometries and need a full non-linear finite element study that zeroes in on their load-bearing capacity. The work starts with layered-shell models to screen all designs, then moves to local 3-D refinement wherever strain or stress peaks appear. Scope of the simulations • Uniaxial tensile loading to global engineering strains of 10 %, 20 % and 30 % relative to the initial end-to-end length. • Additional runs that rotate the load direction so any anisotropy in response is captured. • Large-deformation material and geometrical non-linearities must be included. Key outputs for every geometry • Force-displacement curves and the effective axial stiffness. • Maximum principal strain in materials • von...

I am developing a space-saving cable machine for modern fitness studios and I need a complete mechanical design that turns the concept into production-ready files. The unit must let users perform at least leg curls, and the highest priority on the user side is an effortless adjustable-height mechanism. Above all, I have to be certain the base will remain rock-solid and safe under every condition; stability is the single most critical aspect of the build. Core performance targets • 120 kg adjustable weight-stack resistance driven by a low-friction pulley network. • Structural steel or aluminium frame whose worst-case deflection stays below 2 mm with a global factor of safety of 2.5 or higher. • Optimised pulley diameters, cable routing and bearing selection to keep tra...

I have a petroleum hydro-processing unit that requires a robust reactor model built from the ground up. My immediate priority is model creation rather than plant-wide optimisation, and the focus is strictly on the reactor section handling petroleum-based feedstock. Here is what I need: • A first-principles or data-driven reactor model that captures hydrogen consumption, sulfur/nitrogen removal and catalyst performance under typical HDS/Hydro-cracking conditions. • Calibration against operating data I will provide (feed assays, reactor temperatures, pressures and product qualities). • Well-documented equations or code (Python, MATLAB, gPROMS, Aspen Custom Modeler—whichever you prefer) plus a short validation report comparing predictions with plant data. If you...

I need a qualified stress analyst to run five small-diameter petroleum piping models in Caesar II (or an equivalent program) and demonstrate that they meet ASME B31.4. The welded lines are all 150-lb carbon-steel headers that tie into an API 650 storage tank, and the key outcome is an accurate set of nozzle and shell loads so we can finalise the tank reinforcing pad. Scope of analysis • Build or refine the five provided Caesar models, confirm material and section data, and set up all design temperatures and pressures I will supply. • Apply the seismic acceleration parameters I provide and perform a Response Spectrum Analysis. • Combine those seismic results with temperature and internal pressure cases so the governing load combinations are clearly shown. What I wi...

I have derived the governing equations for a rotating, pre-twisted blade treated as a thin shallow shell and now need a full modal vibration study. The formulation already includes the complete mass matrix, the gyroscopic matrix, and separate stiffness contributions for the structural shell, centrifugal stiffening, rotational softening, and an elastic root represented by spring constants. Thickness varies along the span, so any solution must respect the taper, the twist, and the elastic root support while the tip remains free. Your task is to compute the natural frequencies and mode shapes across a practical range of rotational speeds, capturing the combined influence of centrifugal force, Coriolis coupling, and rotational stiffening. Please work directly from the matrix form I provide, o...

I need a complete ETABS model for a residential high-rise (eight floors and above). All architectural and structural drawings are already prepared, so you will be working from detailed plans rather than guessing the layout. What matters most to me is an accurate 3-D model that reflects the provided column grids, slab thicknesses, wall locations, and load cases. Please set up the full analysis environment—materials, section properties, lateral load combinations, and any required diaphragm assignments—so I can open the file and run checks immediately. Deliverables • ETABS *.edb project file ready for analysis • Brief notes explaining modelling assumptions, load combinations, and any simplifications made If you prefer a particular ETABS version, mention it s...

I need a complete finite-element model of a Warren through truss bridge built in ANSYS (Workbench Mechanical or APDL). The task covers geometry creation, material assignment, boundary conditions and, most importantly, a dynamic study that captures wind and traffic effects. For wind, please implement a realistic fluctuating pressure profile; for traffic, model moving axle loads that travel the bridge length with appropriate speed and spacing. Time-history or transient structural analysis is preferred so that true stress-strain and displacement histories can be extracted. I have only a broad idea of where sensors should sit—mid-span, panel points near supports, and a few along the top chord—so I will rely on your structural-health-monitoring experience to pin down the exact n...
