摘要:<正>The Corrective Smoothed Particle Method(CSPM) is an improvement of the Standard Smoothed Particle Hydrodynamics(SSPH) method.It not only addresses the tensile instability and boundary deficiency problems that have blocked further exploitation of SSPH in structural dynamics,but also enhances the solution accuracy in the whole domain.It has been successfully applied to heat conduction and structural dynamics.In order to test its ability to solve transient problems with heat-structure interaction,in this study CSPM is applied to the governing equations of one-dimensional thermoelasticity.The results of CSPM are compared with the solutions obtained with alternative numerical methods and good agreement is found for the test cases considered. In addition to the advantage of being a gridless Lagrangian approach,CSPM is attractive for coupled problems typically encountered in the areas of fluid-structure interaction,two-phase flow and thermoelasticity.
