能量传递法确定塑性区范围

DETERMINATION OF PLASTIC Z0NE BY ENERGY TRANSFER METHOD

物体受外力产生应变能,此应变能一旦超过其弹性阶段的最大应变能时,物体即进入塑性状态。作者试图把超过最大弹性应变能的应变能量,利用能量传递法向低能量区传递,以确定最终塑性区范围。

When a body is subjected to action of an external force strain energy is in-stored. When the strain energy exceeds the maximum elastic energy limit of thebody, plastic stage occurs in it. In this paper, it is tried to transfer thepart of the strain energy in excess of the maximum elastic value to the lowerenergy-in-stored zone by means of energy transfer method, so as to determineapproximately the final range of the plastic zone.
