Non Linear FEA, Composites

Structural Analysis-Implicit

Innova has strong capabilities in non linear analysis of difficult to analyze materials such as advanced composites.

Using PATRAN Laminate Modeler, there and MSC.MARC, we have the ability to explore many aspects of composite structures, not only in a structural capacity, but in a manufacturing capacity as well.

Structural

  • Simulation of Bonding Delamination
  • Cohesive elements
  • VCCT crack propagation
  • Topology optimization
  • Static Load analysis
  • Dynamic Load analysis

Manufacturing

  • Draping Simulation
  • Spring back prediction (Post Cure)
  • Cure Kinetics Modeling
