Development of hybrid boundary node method in two-dimensional elasticity

In the present method, the source points of the fundamental solution are arranged directly on the boundary. Thus, the uncertain scale factor taken in the Regular Hybrid Boundary Node Method (RHBNM) can be avoided. The parameters that influence the performance of this method are studied through several numerical examples and the known analytical solutions. The treatment of singularity and further integration has been given by a series of effective approaches. The computation results obtained by the present method are shown that good convergence and high accuracy with a small node number are achievable.
