    摘: It is very important to study new numerical methods to solve large deformation problems. In this talk, by using the interpolating moving least-squares (IMLS) method based on a nonsingular weight function to obtain the interpolating function, an improved element-free Galerkin (IEFG) method is presented for solving some large deformation problems. The Galerkin weak form is used to obtain the final discretized equations, and penalty method is applied to impose the displacement boundary condition. The convergence of the numerical solutions of the IEFG method about node distributions and step numbers is discussed. Numerical results of the IEFG method for some large deformation problems show that the IEFG method has great precision, and it can solve large deformation problems effectively.
