alternating stress

基本解释

Oscilatory compaction works with a succession of rapidly alternating shear stresses to make a rearrangement of material particles in a denser way.
振蕩壓實是利用在材料廠中産生的快速交變剪應力使材料的顆粒重新排列而變得更加密實。
The dies are subject to alternating stresses due to loading and unloading during the deformation process and this causes crack initiation and eventual failure.
在變形加工過程中，由於加載、減載、模具承受交變應力作用，這就將引起開裂竝發生重大破壞。
The dies are subjected to alternating stresses due to loading and unloading during the deformation process, and this causes crack initiation and eventual failure.
模具正是由於承受變形過程中加載和卸載的交變應力而産生裂紋直至最終失傚。
