【Abstract】 After analysing the situation of studies on Element-Free Galerkin method (EFG) and some difficulties arising in the process, some ideas aiming at influent radius, basis function and weight function are put forward to further develop EFG, with one of these ideas, EFG with dynamic influent radius, as the focus of the discussion. Moreover, two numeric instances justify the reasonability and feasibility of using dynamic influent radius.更多还原
