New 868-line test file for damage mechanics NEW API (test-driven development):
- Visionary tests for isotropic damage model
- Tests for ductile damage (Lemaitre model)
- Tests for crack band regularization (mesh independence)
- Tests for damage unloading and irreversibility
- Extensive documentation of intended API design
- Tests currently skipped (@test_skip) until implementation complete
- Documents damage variable, effective stress, damage evolution
- Documents regularization and coupled damage-plasticity
This test file serves as both test suite and API design documentation
for the new damage mechanics material model interface.
