| 摘 要： | 应用GMC方法计算了单向纤维加强复合材料在承受不同载荷之后的总体松驰响应。Bodner和Partom的弹－粘塑性统一模型用于描述非弹性相的本构关系，该模型不假设存在屈服条件，也就不必指定加载和卸载条件，可以在加载和卸载的任何时刻使用相同的公式，计算表明，与有限元方法相比，利用GMC方法和统一模型计算单向纤维加强复合材料的总体非弹性响应简单快捷。

| Abstract: | The global relaxation response of unidirectional fiber-reinforced composite material after several kinds of loading is obtained by means of Generalized Method of Cells. The unified elastic viscoplastic theory of Bodner and Partom is used to describe the elastic-plastic behavior of the metal. This theory dose not assume a yield condition, so it is unnecessary to assign loading or unloading criterion, and the formulas can be used at any moment of loading and unloading. The calculations show that the GMC method and the unified theory is suitable to obtain the overall inelastic response of unidirectional fiber-reinforced composite material. |
