| Abstract: | In the paper the bending problem of ribbed panel on elastic foundation is studied by using the Element-free method.The corresponding stiffness matrix of the plate is derived using a variation principle and the moving least squares method,and a computer program is developed.Numerical examples show that the method is feasible and has a promising prospect in engineering practice. |
