Abstract

Stress concentration of the bridge wire specimens with artificial pits were studied by experiments and FEM analysis. Two typical pit shapes were studied : round shape and triangle shape. The stress concentration of the triangle pit and the round pit was obtained by strain gauge measurement and 3D FEM analysis. Both methods agreed very well. Stress concentration factors were calculated for different pit shapes and sizes by FEM. The stress concentration factor of the triangle pit is largest followed by the the round pit. The narrower and deeper pit produces the larger stress concentration factors.
