Basic Structural Non-linearities.
Audience
The basic nonlinearities course is aimed at experienced ANSYS users who wish to enhance their technical capabilities by gaining knowledge of how to perform structural non-linear calculations.
This course forms the first part of the structural nonlinearities training for ANSYS. There are further courses on Advanced Contact & Bolt Pretension, and Advanced Structural Nonlinearities.
Recommended background knowledge
- Engineering degree or engineering experience.
- Familiarity with the ANSYS program (Course S1 or equivalent experience).
Topics Covered
- Overview - types of nonlinearities, FEA issues, general procedure
- Nonlinear Solution - automatic control, results data, solution options, nonlinear options, transient options
- Postprocessing - convergence checking, general postprocessing, time history postprocessor
- Geometric Nonlinearities - types, consistent tangent matrix, preprocessing, solving, postprocessing
- Plasticity - overview, preprocessing, solving, postprocessing
- Contact - concepts, contact wizard, solving, postprocessing, assembly contact
Sample Workshops
- Solution of a shallow arched beam
- Automatic solution controls for a fishing rod
- Restart analysis of a tensile bar
- Convergence enhancement tools applied to a truss structure and a spar
- Postprocessing including using the Results Viewer on a tensile bar specimen

Objectives
After completion, mechanical analysts should have a basic understanding of how to analyse structures with geometric nonlinearities, implement large strain theory in a nonlinear analysis and analyse structures with plasticity and contact nonlinearities.
