摘要
金属结构的裂纹可以用加补强板的方法修补。有限元程序计算表明:选择补强板的参数应按照最大限度降低裂纹尖端应力的原则。文中用实例说明修补裂纹只能延缓裂纹的扩展速度而不能根除裂纹的存在。
A structure with cracks can be repaired by attaching a plate.FEM indicts the dimension of the plate must be choused to minimize the stress of the crack tip.The example shows that crack repairing can only decrease the propagating rate of cracks but cannot eliminate the affection of cracks
