Abstract- In recent years, mesh free methods have attracted more and more attention and regarded as a potential
numerical method in computational mechanics. However, the integrands emerged in these methods are rational
functions and ordinary gauss quadrature does not lead to suitable results as in FEM. But using a polynomial
approximation for integrands over small local quadrature domain, a novel point integration technique is presented for
the LRPIM mesh free method. Radial basis functions (RBFs) which possess the Delta function property are used to
construct shape functions. The accuracy, stability and efficiency of the present method are proved in some numerical
examples.
