It is 100 years since the well-known Mohr-Coulomb strength theory was established in 1900.
A considerable amount of theoretical and experimental research on strength theory of …

A failure criterion typically is phenomenological since few models exist to theoretically derive
the mathematical function. Indeed, a successful failure criterion is a generalization of …

Many geotechnical problems involve undrained behavior of clay and the capacity in
undrained loading. Most constitutive models used today are effective stress based and only …

Comprehensive introduction to finite elastoplasticity, addressing various analytical and
numerical analyses & including state-of-the-art theories Introduction to Finite Elastoplasticity …

The problem of small‐deformation, rate‐independent elastoplasticity is treated using convex
programming theory and algorithms. A finite‐step variational formulation is first derived after …

Fully coupled, porous solid–fluid formulation, implementation and related modeling and
simulation issues are presented in this work. To this end, coupled dynamic field equations …

An extended version of the classical Generalized Backward Euler (GBE) algorithm is
proposed for the numerical integration of a three‐invariant isotropic‐hardening elastoplastic …

This paper presents a constitutive model for fracture simulations in quasi-brittle media within
the framework of zero-thickness interface elements. The present formulation is a 3D …

In this paper, numerical differentiation is applied to integrate plastic constitutive laws and to
compute the corresponding consistent tangent operators. The derivatives of the constitutive …

In this paper, two complex critical‐state models are implemented in a displacement finite
element code. The two models are used for structured clays and sands, and are …
