ABSTRACT
In this paper we combine a meshfree moving least method (MLS) formulation with a Nitsche-like method to enforce essential boundary conditions. The formulation is based on a variational principle. The application in nonlinear structural mechanics involves the Green strain tensor and a hyperelastic material law. Various examples of shell deformations are presented which show the excellent performance of our proposed method.
