复合材料脆塑性力学行为的有限元分析
Finite Element Analysis on Elastic-brittle-plastic the Mechanical Behavior for Composite Material
【摘要】 提出一种适用于脆塑性复合材料的弹脆塑性本构模型.并将该模型引入复合材料结构的力学行为分析中,采用R.Hill的屈服准则,设计了一个完整的复合材料结构弹脆塑性数值计算格式,给出了实验以及计算结果.
【Abstract】 An elastic-brittle-plastic constitutive relationship model is proposed based on experiments, and the model is introduced to elastic-plastic analysis of composite material structure. An elastic-brittle-plastic numerical integral and finite element formulation is designed, and experimental and numerical results are given.
