Abstract

In this paper, the design methods of cruciform specimen of biaxial tensile testing are summarized. In order to study the stress and strain distribution of sheet metal under plastic deformation stage, the specimen shape is designed according to the principles of stress–strain distribution homogeneous in the center area and stress concentrations in the arms. Based on the sample size recommended by the biaxial tensile test international standard tensile properties and the mechanical properties of 45 steel, the simulation model was established. The influence and regularity of the parameters on the test results are calculated by the finite element method, and the optimization is carried out. Optimization results show that thickness of central area can be decreased moderately based on a half of the original thickness, and the best value should be controlled by 40% to 50%; the outward fillet radius can be increased moderately based on the design of slot in arms and thickness reduction in the central area, and the radius value be controlled by 2-7% of specimen width.
