Abstract

A continuum-based micromechanical model is employed for the prediction of the elasto-plastic behavior of periodic microstructural arrays that can generate negative values of Poisson's ratios. The combined effects of the negative Poisson's ratio generated by the array microstructure and the elastoplastic behavior of the constituents are studied. A design methodology for the determination of the constituents' properties of two-phase arrays that generate required values of negative Poisson's ratio is considered.

摘要

基于连续介质的微观力学模型被用于预测能产生泊松比负值的周期性微结构阵列的弹塑性行为。研究了阵列微结构产生的负泊松比与组分弹塑性行为的综合影响。考虑了一种确定能产生所需负泊松比值的两相阵列组分特性的设计方法。
