摘要/Abstract

摘要： 基于ABAQUS平台，建立了开孔复合材料层合板轴向拉伸渐进失效模型.以二维Hashin作为损伤准则，考虑了基体拉伸、压缩失效和纤维拉伸、压缩失效模式.讨论了层合板的受力与失效形式，分析了铺层角度、中心孔尺寸对极限载荷的影响.研究结果表明:失效模式主要表现为纤维拉伸失效和基体拉伸失效，纤维作为复合材料板的主要强度来源，在力与纤维方向发生偏差时，层合板力学性能急速下降；中心孔越大，层合板力学性能越差，并且层合板力学性能与中心孔尺寸成线性关系.

关键词: 复合材料板；轴向拉伸；Hashin准则；渐进损伤；铺层角度；开孔尺寸

Abstract: The progressive failure model of the composite laminate with a hole in the axial tension process was set up based on ABAQUS. The matrix tension failure， the matrix compression failure， the fiber tension failure and the fiber compression failure were considered by selecting two-dimensional Hashin as the damage criterion. The load condition and the failure mode were discussed， and the effects of the ply angle and the size of the center hole on the ultimate load were analyzed. The results showed that the dominant failure modes are matrix tension failure and the fiber tension failure， and the fibers are the strength source of the composite laminate. When the load direction does not agree with the fiber direction， the mechanical performance of the composite laminate degenerates. The mechanical performance of the composite laminate becomes worse as the center hole becomes larger， and is linear with the size of the center hole.

Key words: composite laminate; axial tension; Hashin criterion; gradual damage; ply angle; hole size
