A meshless method for solid mechanics simulation, which includes the following steps: first constructing a trial function and a test function by distributing points according to a geometric shape of a structure; then introducing numerical flux to correct the traditional Galerkin weak form; and finally substituting the trial and test functions into the weak form to construct a global stiffness matrix of the structure and a system of algebraic equations, and solving the system of algebraic equations to obtain displacement and stress of each point, thus completing simulation and analysis of the structure deformation and stress.
