Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] A method for simulation of meshless physical deformation based on least moving squares, comprising the following steps:
[0032] Step (1), the initialization stage performs physical particle sampling on the simulated material geometric model according to a given sampling resolution, and initializes the material properties of the sampled particles;
[0033] Step (2), dynamically update the physical state of each particle in each physical simulation cycle. First, calculate the physical deformation field of the simulated material through the least moving square function, then calculate the displacement gradient of the simulated material, and then solve key physical quantities such as strain and stress based on the displacement field, and then further calculate the elastic body force and volume retention of the simulated material;
