TL;DR: In this work, the energetic formulation for rate-independent dissipative materials is extended to consider non-associative plasticity models, and a clear link between the classical governing equations ofNon-association plasticity and the energetic formulations is established, for which a state-dependent dissipation potential is derived from a generalization of the principle of maximum dissipation.

TL;DR: In this article, a micromechanics-based model is proposed in which the field variables are linked to physical mechanisms at the microcrack level: damage is related to the growth of microcracks, while plasticity is linked to the frictional sliding of closed micro-cracks.

TL;DR: In this article, a series of stress controlled cyclic triaxial tests with different excitation amplitudes and frequencies are performed on a sample composed of a relatively large number of spheres.

TL;DR: In this paper, a complex frequency-shifted version of the Perfectly Matched Layers (PML) is proposed to avoid the evaluation of convolutions, while preserving the second-order temporal character of elastic waves.

TL;DR: In this article, a probabilistic finite element-perfectly matched layers model is developed for the analysis of the dynamic soil-structure interaction problem where the shear modulus of the soil is modeled as a conditional random field.
