Plasticity
In this class the mechanical basics for modeling of strain rate dependent and hyperelastic materials will be suggested. In terms of the modeling of strain rate dependent materials an overview is given of the current time-dependent material models. Also the basics of the material description of hyperelastic materials will be discussed. The speciality of the material description of elastomers lies in the representation of large, reversible contortions, connected with a high non-linear stress-strain-behavior.
Content:
- Basics of the continuum-mechanic
- Vector-/ Tensor Calculation
- Contortion-/ Stress Measures
- Invariants, Main-Axis-Systems
- Potential formulations
- Rheological models: Maxwell, Kelvin-Voigt, 3-parameter solid-state object, 3-parameter, fluid model, generalized models
- Relaxation and creeping
- Multi-axial rheology
- Hyper-elastic material laws
- Blatz-Ko, Mooney-Rivlin, Ogden, Hill Potential
- Incompressibilities
- Identification of hyper-elastic material parameters
- Class examples
Aim of this seminar is the appropriation of theoretical basics, the preparation of numerical solutions of hyper-elastic materials and to get to know hyper-elastic elements and the solver possibilities in LS-DYNA.
