This chapter discusses new material models or changes to existing material models. It provides an overview of the following enhancements:

• “Enhancements to material calibration for hyperelasticity with permanent set,” Section 6.1

• “Selecting multiple items in the Material Library Manager,” Section 6.2

• “Enhancements to the parallel rheological framework,” Section 6.3

• “Import for Johnson-Cook plasticity model,” Section 6.4

• “Strain rate dependence of the yield stress for the nonlinear isotropic/kinematic hardening plasticity model,” Section 6.5

• “Enhancements to the critical state (clay) plasticity model,” Section 6.6
