alternating stress

基本解釋

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(shí)是利用在材料廠中產(chǎn)生的快速交變剪應(yīng)力使材料的顆粒重新排列而變得更加密實(shí)。
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(guò)程中，由于加載、減載、模具承受交變應(yīng)力作用，這就將引起開裂并發(fā) 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.
模具正是由于承受變形過(guò)程中加載和卸載的交變應(yīng)力而產(chǎn)生裂紋直至最終失效。
