Error Simulation Analysis of Gripping Deviation of Plate Specimen Tensile Test Based on Finite Element Method

The plate specimen tensile test is a common material mechanical property test in practical engineering, but the gripping deviation of plate specimen will bring tensile test result an error. In this paper, a finite element model of aluminum alloy notched specimen is built and a static finite element analysis is carried on, the influence of the plate specimen tensile test gripping position deviation rightness of experiment to the test result is studied. The result expresses that the gripping deviation of plate specimen will bring tensile test result an error bigger. It is necessary to raise the accuracy request of the gripping position of plate specimen tensile test.
