New Specimen for Determination of the State of Plane Stress

Abstract:

This paper presents new design of the structural specimen for plane stress analysis. Requirement was that the specimen is loaded by universal tensile testing machine without any special equipment. Specimen was analyzed using finite element method in ANSYS Workbench software. Finite element method was also used for simulation of strain gauge measurement to determine principal stresses, equivalent von Mises stress and orientation of the principal axes in the center of specimen. Finally, experimental stress analysis using strain gauges was performed on real specimen. Results from experimental measurements and numerical simulations were compared.
