Abstract In this paper, general interpolating isogeometric boundary node method
(IIBNM) and isogeometric boundary element method (IBEM) based on parameter
space are proposed for 2D elasticity problems. In both methods, the integral cells
and elements are defined in parameter space, which can reproduce the geometry
exactly at all the stages. In IIBNM, the improved interpolating moving leastsquare method (IIMLS) is applied for field approximation and the shape functions
have the delta function property. The Lagrangian basis functions are used for field
approximation in IBEM. Thus, the boundary conditions can be imposed directly
in both methods. The shape functions are defined in… More >
