Simulation of large deformation, large strain and plasticity effects. Support for nonlinear events to represent cold working and overload/unload/re-load processes. Transition seamlessly from a linear to a non-linear solution process due to the hierarchic simulation structure. Elastic-plastic multi-body contact analysis is also supported.

Allows robust computation of the eigenvalues, as well as the associated mode shapes, for modal (natural frequency) or buckling (load factor) problems. Provide a distinct advantage for eigenvalue and mode shape computation, as locking effects are minimized. Modal analysis can account for pre-stress effects. Buckling analysis can account for pre-load.

Accurately predict the in-plane residual stresses around a single hole caused by mandrel insertion (overload). Removal accounts for subsequent re-loading through linear superposition. Using a simple and intuitive user interface, the user can easily execute a cold work analysis with minimal training and receive feedback regarding the outcome. If it is necessary that multiple holes be cold worked, the Non-Linear solver should be utilized.

Perform margin of safety computations within a non-linear load step solution procedure. Reliable and accurate approach that transcends limitations such as part complexity, non-linearities, and failure criteria, inherent in closed-form solutions and empirically-derived methods. Provides global error estimations and local convergence plots of any quantity of interest.

Perform linear, steady-state heat transfer analysis for metallic and composite bonded structures. Also allows for radiation boundary conditions for non-linear effects, temperature-dependent materials and ability to convert a heat transfer solution into input for a thermo-elastic solution.
