Simcenter Nastran Multistep Nonlinear Solutions 401 and 402 allow you to leverage implicit nonlinear methods to analyze models that include contact; material nonlinearities such as plasticity, hyperelasticity, and creep; and geometric nonlinearities such as large deformations and strain with subcase chaining. These solutions were introduced to replace the legacy SOL 601 Advanced Nonlinear solver and have seen a number of exciting enhancements in recent releases. SOL 401 is implemented in the standard Simcenter Nastran architecture, whereas SOL 402 integrates capabilities from the highly regarded LMS Samtech Samcef solver into Simcenter Nastran. Both solutions feature robust algorithms and are easy to adopt due to their similarity to linear Simcenter Nastran solutions and support from common pre/postprocessors like Femap and Simcenter 3D.

This on-demand webinar describes the basics of nonlinear analysis and demonstrate how to set up a basic plasticity analysis in SOL 401.

Topics:

• Overview of nonlinear structural analysis basic concepts
• Overview of Simcenter Nastran nonlinear analysis capabilities
• Demonstration of setting up and running a basic plasticity analysis on a model that showed yielding during linear static analysis
• Q&A
