Finite Element Method (FEM) Homework Assignment – Simulation & Optimization of Chair Backrest Ended

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... read more

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. read less
