摘要

摘要: 基于ABAQUS软件平台建立穿透挖补修理后混杂铺层层板有限元模型,对修理后层板的拉伸强度和破坏模式进行预测.为验证模型的有效性,对无损伤板和修理后层板进行了试验研究,模型计算结果和试验吻合良好.使用计算模型对修理后结构进行参数研究,比较不同挖补斜度、胶层韧性、胶层厚度、损伤尺寸及附加修理层等设计参数对修理后结构拉伸强度的影响,得到的结果可以为含穿透损伤混杂铺层层板修理设计提供理论指导.

Abstract: Based on the software of ABAQUS,a finite element model was developed in the study of simulating the ultimate tensile strength and failure mode of repaired specimens. To certify the validation of the model, an experimental study was carried out on intact and repaired laminates. The calculated results are coordinate with the tested results very well. Parametric study was conducted on the model to investigate the influence of ultimate tensile strength on changes of scarf ratio, toughness of adhesive, thickness of adhesive, dimension of damage and extra repair plies. The results of the investigation provide insight into the repair design method on hybrid plain woven fabric laminates with penetrate damage.
