Non-Linear Finite Element Analysis of Interconnect Geometries
Budget: €30 – €250 EUR
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 Mises stress
• Strain-energy density maps.
• Spatial distribution of hot spots plus clear identification of yield onset and potential fracture-risk zones.
Tool flexibility
COMSOL Multiphysics preferred.
Deliverables
1. Native solver models for the shell stage and the refined 3-D stage.
2. High-resolution plots and CSV tables for every load case.
4. A concise technical note covering material models, element types, boundary conditions, mesh-convergence evidence and any assumptions made.
