Abstract
Subject headings
Close
- In this paper the parameter identification procedure of a materialmodel for large multiaxial ratcheting strains, as proposed inJohansson et al., (2005), Int J Plasticity 21, 955-980, is demonstrated.In particular, experimental data for uniaxial and biaxialratcheting of carbon steel are considered. The biaxialexperimental data are from Jiang and Sehitoglu, (1994), Int J Plasticity10, 579-608. The material parameters are identified by means ofoptimization algorithms, and a sensitivity analysis is performed.
