## Structural Analysis | Multimatic Inc. - Global Automotive Supplier
//     Engineering

Structural analysis techniques are applied from concept through production design levels.

  • Predicted stress contours are used to analyze material usage and target design improvements.
  • Laminate definition capabilities support Multimatic's composites design.
  • Topology optimization expedites the design engineering process.
  • Chassis torsional analysis highlights critical joints for chassis stiffness.
  • Fatigue analysis is critical in material selection and part life prediction for production components.

For conventional and composite materials, Multimatic’s available methods include linear and non-linear analysis of:

  • Material stress/strain behaviour
  • Large displacements and rotations
  • Contact interaction
  • Temperature changes

Typical studies include component stiffness, strength, buckling, modal (natural frequency) analysis, vibration and fatigue analysis, plus optimization techniques.

Multimatic’s world-class analysis capabilities for composite structures include:

  • Extensive database of reinforced plastics, adhesives and core materials
  • Validated modelling approaches for laminates, sandwich panels and bonding
  • Ability to define and transition laminate definitions between solver codes
  • Direct interface with – and feedback from – manufacturing teams

The company’s optimization techniques, including use of Design of Experiments (DOE) studies, provide:

  • Improved product performance with minimized mass through optimized material distribution within available volumes
  • Early concept direction for product and system topology
  • Improved stamping structural behaviours
