摘要
基于多相固体本构等效理论及相间损伤细观模型,本文分析了颗粒填充复合材料的塑性行为。结合解析表达式和有限元解,给出了含相间损伤变量的宏观初始屈服函数,函数的构成反映了复合材料塑性行为对组分材料物理性质和几何参数的依赖关系,并包含了相间损伤的劣化影响。计算和试验结果的比较表明,本文的理论分析是可靠的。
Based on the constitutive equivalence theory of the multiphase solids and the microscopic model of interficial damage, an analysis for the plasticity of the particulate-composites is completed in this paper. With the combination of theoretical formulations and the numerical calculation the macroscopic initial yield function, including the effects of the physical property of the constituents, the geometric conditions and the interficial damages, is expressed .A comparison between the numerical results and the test values shows the reliability of the theoretical analysis.
