Numerical Modeling of Soil Constitutive Relationship

This book uses numerical methods to model soil constitutive relationships, abandoning the traditional idea of plastic potential. It introduces triaxial compression tests, establishes elastoplastic constitutive equations, and embeds them in a finite element program for verification. The modeling achieves high accuracy.

This book takes a novel approach to modeling soil constitutive relationships by abandoning the traditional notion of solely relying on plastic potential as a means of representation. Firstly, comprehensive triaxial compression tests are conducted on expansive soil, sand, and clay under diverse stress paths. Subsequently, elastoplastic constitutive equations are derived for expansive soil, sand, and clay through numerical modeling techniques, accounting for their stress-dependent behavior. These constitutive equations are then integrated into a finite element program, allowing for their verification through comparison with the finite element calculation results obtained from testing soil samples. The modeling process yields remarkable accuracy, highlighting its potential for accurate representation of soil behavior in a wide range of engineering applications.
