Solid mechanics

AgentFEM keeps the engineering model readable while allowing advanced constitutive and weak-form work to descend into the reusable finite-element layer.

Current routes

Route	Present maturity	Typical use
Linear elasticity	Release workflow	Small-strain static solids and first models
Thermoelasticity	Engineering workflow	Temperature-driven stress after thermal analysis
Compressible Neo-Hookean	Engineering workflow	Finite-strain hyperelastic solids
Mooney--Rivlin	Experimental FEM workflow	Compressible 3D solids and incompressible plane-stress sheets
Mixed displacement-pressure Neo-Hookean	Experimental/engineering	Near-incompressible quadratic tetrahedral solids
Small-strain J2 plasticity	Engineering path	Stateful elastoplastic loading with consistent tangent

Modeling sequence

1. Select the physical study.
2. Create or import the mesh and name physical regions.
3. Declare the displacement field and material.
4. Apply constraints, tractions, body forces, pressure, foundations, or distributed resultants.
5. Select the solution step and incrementation policy.
6. Request standard fields and histories.
7. Accept the result only after the required verification policy passes.
