| 摘 要： | 对复合材料层合板进行了横向静态压痕试验,得到了载荷-位移曲线.依据曲线上的位移值,采用九节点壳单元、三维Tsai-Wu失效判和损伤层刚度折减方法,对准静态压痕损伤进行了计算,并与超声C扫描压痕损伤检测图像做了比较.结果表明,损伤仿真与实际损伤检测图一致性好.

| Abstract: | Tests are performed,measuring load-deformation curves in a fiber reinforced composite laminations subjected to transverse static load.Using 9-nodes shell element and 3-D Tsai-Wu failure criterion and the method of local stiffness depression for damage lamina,the indentation damage of composite laminations is calculated in according to the displacement value of load-deformation curve obtained,and the actual damage shape and size of the laminate are obtained by means of Ultrapact II C-scan device.The results of damage simulation are coincided with the test ones after comparison. |
