Solve the problem of stress focus by reducing sharp corners or locally supplying strength.
解决应力集中主要是通过减少尖角和局部补强来实现的。
Resolve the problem of stress focus don't adopt increasing component dimension, but structure measure by reducing stress focus or locally supplying strength.
解决应力集中问题不应通过加大构件断面尺寸,而应采用降低应力集中的结构措施或局部补强。
