采用APDL参数化设计语言,对损伤结构的裂纹尺寸进行参数化设置,建立含损伤箱形构件有限元模型。讨论损伤箱形构件在拉、弯载荷下的修补效果和复合材料补片铺设方向对损伤构件应力强度因子的影响。
Using APDL parametric design language, the crack size of the damaged structure is parameterized and the finite element model of the box member with damage is established. The effect of repairing box elements under tension and bending load and the direction of composite patch laying on the stress intensity factor of damaged elements are discussed.
