Finite Element Methods for Elastic Contact: Penalty and Nitsche
Tom Gustafsson, Rolf Stenberg
We consider two methods for treating elastic contact problems with the finite element method; the penalty method and Nitsche's method. For the penalty method we discuss how the pen…

Hybrid Nitsche method for distributed computing
Tom Gustafsson, Antti Hannukainen, Vili Kohonen +1
We extend a distributed finite element method built upon model order reduction to arbitrary polynomial degree using a hybrid Nitsche scheme. The new method considerably simplifies…
