Abstract

Roughly speaking, granular media exhibit three basic scales: the specimen scale, the contact scale, and an intermediate scale made up of a set of adjoining particles. In this lecture, we will discuss this latter scale, in a two dimensional context. More specifically, the granular [...]

Abstract

A multiscale model based on finite element (FE) and the Parametric High-Fidelity-GeneralizedMethod-of-Cells (PHFGMC) micromechanical model was formulated and implemented to solve the compression problem in unidirectional IM7/977-3 carbon epoxy composite. The nonlinear PHFGMC governing [...]

Abstract

A boundary element formulation based on the consistent couple stress theory is used to analyze two-dimensional size-dependent piezoelectric response in isotropic dielectric materials. In this approach, there exist a size-dependent piezoelectricity or flexoelectricity effect for centrosymmetric [...]
