Inhalte
Part I: One-dimensional plasticity: formulation and numerical implementation
- Derivation of one-dimensional constitutive equations, building on the phenomenological interpretation of plasticity.
- Strong and weak forms of the initial boundary value problem (IBVP), its discretization and linearization.
- Integration algorithms (return map algorithms) for one-dimensional constitutive equations.
Part II: Three-dimensional classical rate-independent plasticity
- Review of classical governing equations within continuum mechanics and thermodynamics.
- Theory of yield surfaces and classical small-strain plasticity models.
- Maximum plastic dissipation principle and its interpretation as a constrained convex optimization problem.
- Derivation of constitutive equations from convex optimization principles.
Part III: Integration algorithms for plasticity
- Incremental form of constitutive equations and geometric interpretation as closest point projection.
- Radial return map algorithm for J2 plasticity.
- General return map algorithms (closest point projection algorithms, cutting plane algorithms).
