COMO A dedicated special purpose program Como has been developed which is able to fit elasto-plastic material models on a set of experiments. The user can specify the results of several types of experiments, the large deformation description to be used, and the specific elasto-plasticity law to be fitted. The program then automatically searches for the best fit of parameters in the law, in a least squares sense. Presently the following experiments can be used: - simple shear - pure shear - uniaxial tension - oedometric compression - hydrostatic compression Presently the following deformation models can be used: - engineering strains - Jaumann strains |
