摘要
建立了复合材料层合板三维连续介质损伤力学模型,并将该模型应用于复合材料开口层合板的损伤破坏分析中。与相关试验中开口层合板强度和损伤破坏情况对比分析表明:本文模型能够有效地模拟开口层合板从初始损伤到完全破坏的全过程,具有较高的计算精度和良好的数值模拟收敛性。基于该模型,详细分析了在单向拉伸载荷作用下开口层合板不同铺层的损伤破坏情况。
A 3D continuum damage mechanics （CDM） model was applied for predicting the strength and damage evolution of notched composite laminates. Comparing the analytical results with the experimental data, the model in this paper is capable of simulating the damage evolution of notched composite laminates from initial damage to final collapse, and has high accuracy and good calculation convergence. Based on this effective model, the damage propagation of each layer under uniaxial tensile loading condition was analysed.
