Abstract :
The aim of this study was to show that the problem of weakening a structure as the result of local excess stress can be solved by a modification of the geometric shape of the weakened area. To address this, it is necessary to know the stress concentration factor associated to each hole shape. The concept is hereby discussed to propose the best shape which meets the criterion of resistance during the design phase. The case of the traction of a breakthrough plate with a hole is detailly analyzed before other hubs discussions such as the shoulders. The strategy will support the numerical analysis code COMSOL of the field stress at the level of singularities.
