New file: src/assemblers/material_cache.jl (247 lines)
Features:
- Parametric MaterialStateCache{StateType}
- Stores stress tensors (σ)
- Stores tangent modulus tensors (𝔻)
- Stores material state history (state, state_new)
- update_material_cache! function
State management:
- EmptyState for stateless materials (LinearElastic)
- Custom state types for plasticity (J2PlasticityState, etc.)
- State evolution tracked across load increments
Type parameter:
- StateType: Material state type (EmptyState, J2PlasticityState, etc.)
- Enables type-stable state access
Also includes ImmutableMaterialStateCache for read-only views
with @inline accessor functions.
