摘要
本文改进了Whitney的点应力准则,在距孔边一特征长度的圆周上应用Tsai-Wu张量准则.改进后的准则可应用于非对称铺层含孔板,并且除了可以确定含孔板的破坏强度,也可以确定孔边开裂位置,应用这一方法对含圆孔的偏轴板拉伸进行了分析,并与实验作了比较,二者吻合较好.
The strength criteria based on the point stress criteria and Tsai-Wu tensor polynomial criteria is presented for predicting the uniaxial tensile strength of off-angle laminated plates containing circular cutout.Both failure strength and failure location of off-angle plate with circular hole can be determined by the improved point stress criteria.Theoretical analysis and experimental investigation were conducted on glass/epoxy.The good agreements between theoretical and experimental results have been obtained.
