Stress State Evaluation in Biaxially Loaded Cruciform Specimens

Abstract:

Testing cruciform specimens under static biaxial loading conditions is the method with the best results used to determine the mechanical behavior of materials. A static stress with nonlinear material analysis was applied for only one-eighth of the specimen geometry, due to symmetry conditions, to evaluate stress state from different cruciform specimens subjected to equi-biaxial tension. For the majority of isotropic materials with ductile behavior, such as metals, the most suitable yield criterion used to predict failure is von Mises.
