A boundary point interpolation method for stress analysis of solids

摘要: A boundary point interpolation method (BPIM) is proposed for solving value problems of solid mechanics. In the BPIM, a problem domain represented by properly scattered nodes. The integral equation (BIE) 2-D elastostatics has been discretized using interpolants based only on group arbitrarily distributed points. present BPIM formulation, shape functions constructed polynomial basis function in curvilinear coordinate possess Dirac delta property. conditions can be implemented with ease as conventional element (BEM). coded FORTRAN, and used to obtain numerical results stress analysis two-dimensional solids.
