Cut Bogner-Fox-Schmit elements for plates [PDF]

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2020
AbstractWe present and analyze a method for thin plates based on cut Bogner-Fox-Schmit elements, which are$$C^1$$C1elements obtained by taking tensor products of Hermite splines. The formulation is based on Nitsche’s method for weak enforcement of essential boundary conditions together with addition of certain stabilization terms that enable us to ...
