Abstract

The boundary element method is applied to elasticity problems in two- dimensions. The boundary is discretized into straight boundary elements. Second order polynomials are used to represent displacement and traction on each element. Length of each element is determined by utilizing a spline-based grid optimization scheme. Various error norms are controlled based on the equilibrium conditions. The performance of the optimization scheme is assessed and convergence patterns are demonstrated.
