Abstract
PB-spline is introduced in isogeometric BEM schema for solution of 3-D linear elasticity problems. In this schema, bivariate PB-spline is employed not only to construct the exact geometric model but also to approximate the boundary variables. PB-spline as an unstructured spline technology can largely reduce the computation cost for analysis of some special geometric models, such as a sphere, where lots of nearly singular and singular integrals will appear. Numerical tests for a sphere and a tube, show that the new method has good performance.
