Abstract

The problem of stretching a plate with a central or lateral crack is considered. The previously obtained solution, which determines the stresses in the plate in the vicinity of the central crack, is used to predict the load at which plastic deformation appears in the plate with a lateral crack. The Mises condition is used as a criterion for plasticity. The calculation results are compared with the experiment carried out on plates made of aluminum alloy, brass and steel.

确定带有裂纹的拉伸板中出现塑性变形的载荷

摘要

考虑了拉伸具有中心或横向裂纹的板的问题。先前获得的解决方案（用于确定中心裂纹附近的板中的应力）用于预测在具有横向裂缝的板中出现塑性变形的载荷。Mises条件用作可塑性的标准。将计算结果与在铝合金，黄铜和钢制成的板上进行的实验进行比较。
