When the finite element method is used in structural analysis, the problem of extremely low analysis accuracy due to poor quality mesh partitioning has been a concern, and mesh-free analysis methods that do not depend on mesh partitioning for calculation accuracy have been proposed. The Fragile Points Method (FPM) is proposed as one of the mesh-free methods suitable for large deformation analysis, offering the advantage of performing analyses without suffering from the deterioration in analysis accuracy due to the degradation of mesh quality associated with large deformations. In this study, the numerical solutions of the FPM for small deformation elasto-plastic problems were obtained, and their accuracy was evaluated.
