Experiments on yielding of tension specimens with notches and holes

The yield loads of various ST-37 steel strips with notches and holes, subjected to tension, are determined experimentally. All samples have the same thickness and the same net cross-sectional area. Their width-to-thickness ratio is such that they are assumed to be in a state of plane stress. Essentially, the experiments are performed to find the effect of the angle of the V-notched specimens on the yield load, the most efficient shape of cut-outs and the effect of eccentricity of circular holes on the carrying capacities of the strips. The results are then compared, whenever possible, to the existing theoretical results.
