Simulation of Isotropic Cyclic Compression by an Elasto-viscoplasitc Constitutive Model Based on the Nonlinear Kinematic Hardening Rules

Oka, Fusao / Kimoto, Sayuri

A cyclic elasto-viscoplastic constitutive model is proposed for saturated soils based on the nonlinear kinematic hardening rules by considering the structural degradation of soil particles. The model is based on the overstress type elasto-viscoplasticity theory and includes deviatoric and volumetric components of kinematical hardening parameters. The performance of the model is verified through the isotropic cyclic compression test of soft clay samples. The simulated results with both the linear and non-linear kinematical hardening can well simulate the cyclic compression behavior of clay, which indicates the capability of the proposed model to reproduce the cyclic behavior of soft clayey soils.
