| چکیده | ||
| The obstacle problem is a speci fic type of contact problem that can be formulated as a variational inequality or complementary problem in function spaces. Such problems often yield non-smooth solutions, making it challenging to fi nd a suitable numerical approximation. In this paper, we present a meshfree method for numerically solving an obstacle problem. In proposed method the interpolating moving least square approximation is utilized in element-free Galerkin approach. Implementing this method on a computer is straightforward and effective. To ensure the effciency of the proposed method, we have investigated the convergent of the proposed method . Additionally, we have solved several examples of the obstacle problem using the proposed method. The numerical results obtained con firm the theoretical achievements and demonstrate the method's effectiveness and accuracy. | ||
