Modeling scope

• Model setup that mirrors the test

  • Geometry fidelity where it matters (grips, tabs, fillets, bondlines, constraints)

  • Correct boundary conditions (load introduction, contact, sliding, friction, clamping)

• Material modeling & calibration

  • Orthotropic composite behavior (lamina/laminate level)

  • Progressive damage / failure onset calibration using test evidence

  • Hybrid stacks (metal + composite) with attention to stiffness mismatch and interface effects

• Interfaces & bonding

  • Tied / cohesive / traction–separation concepts as needed

  • Failure mode matching: adhesive vs cohesive vs interlaminar

• Correlation workflow

  • Stress–strain response, stiffness, failure onset, and localization patterns

  • Sensitivity studies to quantify uncertainty and margins

Tools & approach

• Experienced with implicit and explicit FE solvers and the practical tradeoffs between them (stability, runtime, contact, failure, and convergence).

• Comfortable building material cards and calibration loops from coupon data to component-level models.
