摘要
利用细观力学平均应力场理论和割线模量,本文给出了分析复合材料弹塑性能的统一模型,并详细地分析了单向增强、平面、空间任意取向、叠层等复合材料,弹性、屈服、硬化性能与微观结构的关系.模型预测结果与实验值吻合较好.
A unified micromechanical model is proposed to predict the elasto-plastic properties of composite materials. The theory is based on the mean stress field and secant modulus concepts. The influence of the microstructural parameters on the composite elastic stiffness, yielding and strain hardening are analyzed in details. The modeling results agree well with experimental data given in literature.
