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.
