Year: 2025
Type: article
Abstract: To find a reliable and universal plastic deformation mode of circular plates under impact loading, based on the energy method, a plastic deformation calculation model for circular plates under impact loading was established, with different deformation modes and material strain rate effects considered. Then the calculation model was compared with the experimental results to analyze the calculation deviation of plastic deformation of circular plates under different deformation modes. The results show that, different deformation mode assumptions give different spatial distributions of membrane tensile strain and different membrane tensile average strain rate effects, which changes the energy absorption characteristics of plastic deformations and finally affects the plastic deformation values of circular plates. The parabolic deformation mode has the advantages of small errors and wide application ranges for materials, and is suitable for the subsequent engineering evaluation.
