Abstract:  The standard methodology for the identification of the parameters of CDM models is long and difficult both from the numerical and experimental viewpoints. Indeed, even the simpler models require specific tests (a series of ramps) and significant post-processing. In this work we propose an inverse calibration approach based on a simple tensile test. In fact, most CDM models imply a coupling between the damage and the true-stress true-strain curve. Thus by minimizing an error functional it is possible to solve the inverse problem.
