Modeling of a three-point bend test of a beam made of AW 5083 alloy

Abstract

The paper describes the modeling of a three-point bend test carried out on a beam made of the AW 5083 aluminium alloy performed using the finite element method. The three-point bend test was carried out experimentally in accordance with the current standard PN-EN ISO 7438:2016-0. During the test, the values of the beam material constants, such as Poisson number and Kirchoff modulus which were necessary for the modeling were determined. The results obtained in the test allowed for modelling using software based on the finite element method, such as MSC Patran and Abaqus software. The test modelling in the software was performed taking into account the beam geometry, the material properties, the boundary conditions, and the load. In order to verify the model, a comparative analysis was performed of the values of the bend of the beam’s central axis obtained from the experiment and the values obtained after the FEM modeling and those obtained by the analytical method.
