Extension of a Basic Hypoplastic Model for Cohesive Soils
Abstract A study on the extension of a basic hypoplastic constitutive model for cohesive soils is presented. Firstly, a translated tensor function is added to the constitutive equation to simulate the effect of cohesion. In addition, the magnitude of the translated tensor is linked to cohesion and internal friction angle of cohesive soils. Secondly, the concept of strain history is incorporated to capture strain softening behaviour of cohesive soils. Finally, the extended model is implemented into a finite element code, and some boundary value problems are simulated to examine its performance.
