Abstract

In the framework of the couple stress theory, we discuss the effective elastic properties of a metal open-cell foam. In this theory, we have the couple stress tensor, but the microrotations are fully described by displacements. To this end, we performed calculations for a representative volume element which give the matrices of elastic moduli relating stress and stress tensors with strain and microcurvature tensors.

耦合应力理论框架下泡沫的有效特性

摘要

在耦合应力理论的框架内，我们讨论了金属开孔泡沫的有效弹性。在此理论中，我们具有偶应力张量，但微旋转由位移完全描述。为此，我们对具有代表性的体积元素进行了计算，给出了将应力和应力张量与应变和微曲率张量相关的弹性模量矩阵。
