Research Initiation: A Micromechanics Analytical Model for Characterizing Sublaminate Damage

本研究的目的是预测断裂行为的一个 含裂纹和脱粘的纤维增强复合材料层合板。 应力滞后理论将被用来表示应力-位移 关系和故障将通过使用 细观力学强度理论 故障预测将是 通过实验室实验的适当数据进行验证。 的 这项研究的结果将有可能改善 了解几种类似复合材料的破坏行为 系统.

The objective of this research is to predict the fracture behavior of a fiber reinforced composite laminate containing cracks and debonding. The stress lag theory will be used to represent the stress-displacement relationships and the failure will be investigated by using a micromechanics strength theory. The failure predictions will be verified with appropriate data from laboratory experiments. The results of this research will have the potential to improve the understanding of the failure behavior of several similar composite systems.
