- Abstract
- In this paper, we study plane incompressible elastic problems by means of a ''stream-function'' formulation such that a divergence-free
displacement field can be computed from a scalar potential. The numerical scheme is constructed within the framework of NURBS-based
isogeometric analysis and we take advantage of the high continuity guaranteed by NURBS basis functions in order to obtain the displacement
field from the potential differentiation. As a consequence, the obtained numerical scheme is automatically locking-free in
the presence of the incompressibility constraint. A Discontinuous Galerkin approach is proposed to deal with multiple mapped, possibly
multiply connected, domains. Extensive numerical results are provided to show the method capabilities. (literal)
