Data analysis of three-point bending deformation based on finite element method

The three-point bending experiment is widely used to evaluate the mechanical properties of materials under bending loads. However, traditional testing methods have limitations in terms of data acquisition. To overcome these challenges, this study aims to develop an accurate finite element model of the three-point bending test using Abaqus software. The model is utilized to data analyze bending specimens made of aluminum alloy and carbon steel. The simulations provide stress/strain distributions that are not easily obtained through experiments, and the displacements of nodes at different locations are statistically calculated to accurately capture bending deformations. The flexibility of the model allows for adjustments in specimen parameters to explore the bending resistance of different materials, as well as modifications in specimen dimensions to provide a comprehensive evaluation of mechanical properties for various cross-sections under bending loading.
