Abstract The Nitsche’s method is originally proposed as a technique to impose boundary conditions, nowadays it is
widely used for isometric analysis (IGA) and corresponding topology optimization applications. Based on
our previous research [1], we present a simple way to derive the Nitsche’s formulations for different kind of
boundary and interface conditions, and studied this technique in the context of IGA discretization, especially
for patch coupling and contact problems. The skew-symmetric variant of the Nitsche’s method is then
further studied. For linear boundary or interface conditions, the skew-symmetric formulation is parameterfree. For contact conditions, it remains stable and accurate for a… More >
