Nonlinear assessment of elastomer and spring assemblies

Nonlinear structural models assessed deformation, contact and load transfer in compact spring, bump-stop and elastomer assemblies.

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.
