Perfect Jacobian for large deformation J2 plasticity with nonlinear hardening

6

## Reason We don't currently have a non-AD version plasticity stress update (with nonlinear hardening) with perfect Jacobian. ## Design Derive and implement the perfect Jacobian in the new mechanics...

## Reason For better compatibility with old kernels, the new kernels should support 1. plane strain 2. weak plane stress 3. generalized plane strain ## Design 1. Plane strain is...

## Reason Currently, we can use `ElementJacobianDamper` or `ReferenceElementJacobianDamper` to limit the change of element volume between nonlinear iterations. The maximum element volume change is computed over the entire domain....

Add domain form J integral

1

- Add domain form J integral - Add J integral correction term due to pressure - Rename PhaseFieldJIntegral to JIntegralContourIntegral - Add a tutorial for J integral close #121

## Reason Domain form J integral is more flexible and accurate. It also plays nicely with phase-field regularization. ## Design Add two new classes for domain form J integral. One...
