The Johnson-Cook (J-C) constitutive model is widely used in the finite element simulation, as this model shows the relationship between stress and strain in a simple way. In this paper, a cluster global optimization algorithm is proposed to determine the J-C constitutive model parameters of ...

All the constitutive parameters could be quickly identified by the local search optimization algorithm taking least squares method as the object function. By adopting a stress compensation updating algorithm, a subroutine VUAMT of the proposed constitutive model was programmed on plat of ABAQUS/Explicit...

Since material erosion is a complex phenomenon, often including high strain/strain-rate deformations and failure/damage processes, it is crucial to use appropriate and validated material constitutive models in order to model erosion process. The work presented in this paper is motivated by this goal...
