Multi-scale models enriched with the second gradient of the displacement field and based
on the concept of representative volume element (RVE) are examined and discussed in …

In this contribution, the enforcement of uniform traction (UT) and periodic boundary (PB)
conditions on arbitrarily generated meshes is analysed in detail, and the derivation of the …

An efficient and general multiscale strategy to model rough contact and determine the
evolution of the real contact area is proposed, based on the splitting of the surface power …

The convergence behaviour of representative volume elements (RVEs) with an increasing
number of crystalline grains, which can undergo crystallographic slip and mechanically …

Purpose The purpose of this research is to establish a robust numerical framework for the
calibration of macroscopic constitutive parameters, based on the analysis of polycrystalline …

Purpose The present paper aims to explore a computational homogenisation procedure to
investigate the full geometric representation of yield surfaces for isotropic porous ductile …

Purpose This paper proposes a unified original general framework, designed to theoretically
develop and to extremely easily implement elastoplastic constitutive laws defined in the so …

The analytical criterion proposed by Gurson is an important reference for modeling the
plastic behavior of porous ductile media. However, the Gurson model assumes a simplified …

The aim of this work is to determine an effective yield criteria for porous pressure sensitive
solids by employing a virtual testing strategy. The focus is on the pressure sensitivity …

In virtually every structural, mechanical and biological system, it is by way of contact that
bodies interact, coming in to touch and interchanging energy. Despite being something …
