Elasto-Plastic Mindlin Plate Analysis
Definition
Elasto-plastic Mindlin plate analysis models plate bending with transverse shear deformation while allowing material yielding through the thickness.
How It Works
The source treats Mindlin plate bending with both nonlayered and layered plasticity idealizations. The layered view is important for implementation: each layer or through-thickness integration point can have a different stress state and plastic history, so yielding can spread through the thickness as the moment increases.
The source limits the plate plasticity treatment mainly to Tresca and von Mises yield criteria. That makes the page a structural counterpart to Plasticity Yield Criteria and a useful bridge from continuum plasticity to shell and plate elements.
Why It Matters
Plate and shell plasticity require more than a material law. The solver must also decide how section integration, transverse shear, bending resultants, and through-thickness state variables are represented.
Connections
MITC4 Shell Element and Abaqus Structural Element Families provide the shell/plate element context. Abaqus Beam and Shell Section Definitions is the production counterpart for thickness, layers, section points, and material assignment.
