Abstract :
In the current research work, we present an improvement of meshless
boundary element method (MBEM) based on the shape functions of radial basis
functions-QR (RBF-QR) for solving the two-dimensional elasticity problems. The
MBEM has benefits of the boundary integral equations (BIEs) to reduce the dimension
of problem and the meshless attributes of moving least squares (MLS) approximations.
Since the MLS shape functions don’t have the delta function property, applying
boundary conditions is not simple. Here, we propose the MBEM using RBF-QR to
increase the accuracy and efficiency of MBEM. To show the performance of the new
technique, the two-dimensional elasticity problems have been selected. We solve the
mentioned model on several irregular domains and report simulation results.
