Engineering question

Large deformation, nonlinear material response and changing contact had to remain interpretable through force-displacement and local-demand results.

Model & approach

  • Represent elastomer or spring behaviour together with contact interfaces
  • Evaluate load paths, deformation shapes and local stress regions throughout travel

Boundary conditions

  • Geometric and material nonlinearity
  • Contact, preload and project-specific attachment stiffness

Results of the assessment

  • The models separated global force-displacement behaviour from local contact and stress effects.
  • Geometry and support conditions governed where deformation and load concentrated.

Engineering consequence

The assessment supported refinement of form, stiffness and attachment details.
