The verification tests in this section consist of one-element models that are subjected to monotonically increasing tensile loads in sequential import analyses. Two sequences of tests are performed. The first sequence involves transferring results from Abaqus/Explicit to Abaqus/Standard and then again to Abaqus/Standard; the second involves transferring results from Abaqus/Standard to Abaqus/Explicit only. In the analyses an elastic-plastic material with Mises yield criterion is used in conjunction with ductile, shear, FLD, FLSD, and MSFLD damage initiation criteria and displacement or energy-based damage evolution laws.
The following material properties are used (the units are not important):
- Material 1:
- Elasticity
Young's modulus, E = 2.0 × 1011
Poisson's ratio, = 0.33
- Density
