In the past few decades, extensive research on concrete modeling to predict behavior, crack
propagation, microcrack coalescence by utilizing different approaches (fracture mechanics …

Many plastic second gradient models have been developed in the last 10 years. However
some plastic second gradient models are nonlocal ones. This paper is an attempt to give a …

A large strain finite element formulation based on a local second gradient plasticity model is
presented. The corresponding constitutive equations were developed as a direct extension …

This paper presents the state of the art of the theory of rock damage and healing mechanics,
with a particular emphasis on the strategies available to relate the micro-scale of crystals …

Just like all constitutive models involving softening, Gurson's classical model for porous
ductile solids predicts unrealistic, unlimited localization of strain and damage. An improved …

In the present paper, a constitutive model for the description of the dissipation in the
concrete is provided. The theoretical description is based on a micromorphic model in which …

Modeling strain localization with a second gradient model can become problematic at the
late stages of softening response, when the second gradient terms become significant …

Being a quasi-brittle material, concrete under tensile loading exhibits a strain softening
behaviour that cannot be accurately reproduced with classical (without an internal length …

We presently construct effective second-order grade anisotropic continuum models
equivalent to initially discrete periodic beam lattices. This entails the construction of a …

In this paper, an extension to the finite deformation regime of the infinitesimal theories of
strain gradient plasticity discussed in a paper by R. Chambon, D. Caillerie and T …
