Abstract
- Multiple pre-strain based cyclic stress-strain curves are generated.
- These multiple cyclic stress-strain curves are applied in a single simulation.
- Each curve is recursively assigned to groups of elements with specific plastic strain level.
- The properties of elements are therefore updated after each increment.
- Validation of the springback prediction with real experiments for two geometries.
