本文基于称为有限体积直接平均微力学 (FVDAM) 理论的先进均质化模型，通过代表体积元 (RVE) 评估单向层合复合材料在横向拉伸/压缩载荷下的横向损伤萌生和扩展。在确定纤维-基体界面脱粘和基体开裂时，RVE 中考虑了纤维、纤维-基体界面和基体相。模拟断裂模式与实验观察结果非常吻合。
The transverse damage initiation and extension of a unidirectional laminated composite under transverse tensile/compressive loading are evaluated by means of Representative Volume Element (RVE) presented in this paper based on an advanced homogenization model called finite-volume direct averaging micromechanics (FVDAM) theory. Fiber, fiber-matrix interface and matrix phases are considered within the RVE in determining fiber-matrix interface debonding and matrix cracking. The simulated fracture patterns are shown to be in good agreement with experimental observations.
