About the job
Project Description:
I am looking for a qualified mechanical engineer or FEM expert to complete a university homework assignment using the Finite Element Method (FEM).
This is not a simple mesh task – the work involves CAD-based FEA modeling, simulation, optimization, hand calculation, and technical documentation.
Project Details:
You will be working on the backrest of an aluminum chair, provided in .STEP CAD format. The following tasks are required:
Task 1: Model Setup
Create a 2D PSHELL model (12 mm thickness) using the provided CAD data.
Apply a high-quality mesh (less than 1% tria elements, under 15,000 total elements).
Define boundary conditions and simulate two load cases (leaning and sitting).
Determine the weight of the backrest and provide a critical assessment of the mesh, load application, and constraints.
Task 2: Simulation
Run FEA for both load cases.
Plot displacements and von Mises stress distributions.
Identify maximum values and their locations.
Evaluate the safety factor against yielding.
Task 3: Hand Calculation
Perform a simplified hand calculation of deformation based on TM2 approach.
Compare the hand calculation to the FEA result and explain any deviations.
Task 4: Optimization
Redesign the backrest to achieve at least a 20% weight reduction.
Maintain the same material (EN AW-6082 Aluminum).
Ensure deformations are no greater than the original design and that a sufficient safety factor (>1) is ma...

Maintain the same material (EN AW-6082 Aluminum).
Ensure deformations are no greater than the original design and that a sufficient safety factor (>1) is maintained.
Plot updated displacements and stress results.
Task 5: Load Capacity
Determine the maximum load that causes:
a) A deformation of 3 mm
b) A safety factor equal to 1
Final Deliverables:
PowerPoint presentation with clear, self-explanatory slides
One section per task, with relevant plots, stress results, displacements, and conclusions
Executable .fem files for each task (no .hm, .mvw, .h3d, etc.)
Optional: Excel summary showing model versions and parameter changes
Tools Required:
HyperMesh and HyperView (preferred)
SolidWorks or CATIA (for CAD editing, if needed)
Strong background in FEA and mechanical engineering
Ability to write clearly and technically in English
Deadline:
July 10, 2025
Notes:
This is a university homework assignment where collaboration with experienced freelancers is allowed.
The final output must be original and self-explanatory. No copied or AI-generated reports will be accepted without proper engineering logic and justification.
