Numerical simulation of impulse waves in Cosserat media based on a time‐discontinuous Galerkin finite element method

The time‐discontinuous Galerkin finite element method (TDGFEM) has advantages in reducing spurious numerical oscillations and capturing discontinuities of solutions in space for high‐frequency dynamical problems. This article extends TDGFEM into Cosserat media to focus on impulse wave propagations, involving rotational wave and effects of microstructures. The Cosserat continuum theory contains additional rotational degrees of freedom, leading to...
