Abstract
It is well known that the boundary integral equations of linear elasticity are exact mathematical representations of the governing differential equations when the integrals are written over closed surfaces (or closed curves in plane problems). However, practical geometrical design technics (namely, NURBS curves and surfaces) often do not render a perfectly watertight boundary representation of the domain. Thus, non-watertight boundary geometries with small gaps are often generated. In the present study, one investigates how such unsought gaps affect the response of boundary elements models. The obtained results have pointed out that, as long as the gaps are small enough, non-watertight boundary geometries may produce valuable solutions for practical purposes.
