This chapter discusses the structural material nonlinearities of plasticity, creep, nonlinear elasticity, hyperelasticity, viscoelasticity, concrete and swelling. Not included in this section are the slider, frictional, or other nonlinear elements (discussed in Element Library) that can represent other nonlinear material behavior.
The following topics are available:
- 4.1. Understanding Material Nonlinearities
- 4.2. Rate-Independent Plasticity
- 4.3. Rate-Dependent Plasticity (Including Creep and Viscoplasticity)
- 4.4. Gasket Material
- 4.5. Nonlinear (Multilinear) Elasticity
- 4.6. Hyperelasticity
- 4.7. Bergstrom-Boyce
- 4.8. Mullins Effect
- 4.9. Viscoelasticity
- 4.10. Swelling
- 4.11. Cohesive Zone Material (CZM) Model
- 4.12. Fluid Material Models
