the dies are subjected to alternating stresses due to loading and unloading during the deformation process, and this causes crack initiation and eventual failure.
模具正是由于承受变形过程中加载和卸 载的交变应力而产生裂纹直至最终失效。
an investigation of the effects of mean and alternating stresses on short fatigue crack growth under uniaxial loading is reported.
在短期单轴载荷下的疲劳裂纹扩展的意思,交变应力的影响的调查报告。
the dies are subject to alternating stresses due to loading and unloading during the deformation process and this causes crack initiation and eventual failure.
在变形加工过程中,由于加载、减载、模具承受交变应力作用,这就将引起开裂并发 生重大破坏。
