In this paper an application coupling the Isogeometric Boundary Element Method with the continuum damage mechanics is proposed in three-dimensional geometry. The novelty of the approach stands both in the discretization phase in which independent NURBS functions are used to model geometry plus governing variables and in the computation step where a special mapping procedure is applied to compute the arising volume integrals.

Abstract
In this paper an application coupling the Isogeometric Boundary Element Method with the continuum damage mechanics is proposed in three-dimensional geometry. The novelty of the approach stands both in the discretization phase in which independent NURBS functions are used to model geometry plus governing variables and in the computation step where a special mapping procedure is applied to compute the arising volume integrals. The the use of the internal cells is avoided. The implementation is verified on a simple test case.File in questo prodotto:
