ABSTRACT
In this paper, we derive explicit expressions for the penalty parameters appearing in symmetric and semi-symmetric interior-penalty discontinuous Galerkin finite element method (DGFEM) for fourth-order elliptic problems. We demonstrate the sharpness of the theoretically predicted penalty parameter values through numerical experiments.

    Currently, commercial finite element codes for elastodynamics problems use a finite difference approximation in time and a finite element approximation in space. There are two disadvantages to existing methods: 1) extremely small integration time steps (e.g., nanoseconds) are necessary due to...
