Anisotropic Bounding Surface Model in ABAQUS Software

Abstract:

This paper presents an improved anisotropic bounding surface model which is based on Wheeler’s elastoplastic model (S-CLAY1). The developed model is programmed in ABAQUS software by writing UMAT subroutine, which is integrated in Return Mapping Algorithm. The parameters sensitivity analysis is implemented on plastic modulus. The study shows that the developed anisotropic bounding surface model is capable of describing the dynamic properties of soft clay.
