Nonlinear static and transient response

Analyze structures that exhibit nonlinear behavior. Nonlinear effects can be the result of nonlinear material properties, large deformations, and contact-based changes in the boundary conditions. Most physical phenomena contain some kind of nonlinear effect. 

Key capabilities include:

  • Material nonlinear, including plasticity (Ohsaki and Ramberg), nonlinear elasticity, large strain hyper-elastic, large strain isotropic, thermo-elasticity, temperature dependence, creep, brittle materials, shape memory materials.
  • Geometric nonlinear.
  • Gap, slide line, and surface-to-surface contact, with surface contact weld failure and friction support.
  • Progressive Ply Failure Analysis.
  • Tension-only shell and cable elements.
  • Direct nonlinear solutions for buckling, pre-stress, and transient response.
  • Automated Surface Contact Generation.
  • Automated Edge Contact Generation.

Nonlinear analysis can include static loadings that produce nonlinear effects, as well as transient loadings that can show the evolution of the model through time.
