本文对平面应力Ⅰ型裂纹体的塑性区尺寸和形状作了讨论,以图表方式给出了精确解的数值结果。在考虑到裂纹顶部应力有限这一事实后,对塑性区尺寸进行了修正,并对解作了简单的讨论。
In this paper, the size and shape of the plastic zone of the plane stress I-type crack body are discussed, and the numerical results of the exact solution are given graphically. Taking into account the fact that the stress at the top of the crack is limited, the size of the plastic zone is modified and the solution is briefly discussed.
