| 摘 要： | 本文对单向连续纤维增强复合材料的弹塑性本构关系进行了数值模拟。首先提出了基于统一弹粘塑性本构理论的有限无法,然后利用微观力学模型研究了弹性纤维增强弹粘塑性基体的复合材料应力——应变关系。

| Abstract: | In the paper the elastoplastic constitutive relations of unidirectional fiber reinforced composite materials were modeled numerically. The finite element method based on elastic-viscoplastic constitutive theories was presented, then the micromechanics model was used to study the nonlinear stress-strain relations of composites cf which the elastic-viscoplastic matrix is reinforced by the elastic fibers. |
