Stress distribution near a rectangular hole in a weighted massif
Abstract
We consider a plate weakened by a central curvilinear opening, in shape very close to a rectangle with the aspect ratio a:b=2 (a is the vertical, b is the horizontal side of the opening). In the curvilinear contour (Fig. 1), the ratio a:b represents the ratio of the center lines; hereafter we will call this ratio the ratio of the sides for brevity. The plate is subjected to the following loads (see the article). We shall confine ourselves to the study of the contour stresses, which are known to have maximum values, and give general considerations on the zone of influence of the hole. The work is intended to enable designers to use in their practical work a scientifically sound solution.
