Strong imposition of Dirichlet boundary velocities in structure-preserving discretizations of elastodynamics

Cristobal Ponce, Hector Ramirez, Yongxin Wu +2

The paper proposes a method to strongly enforce Dirichlet boundary velocities in finite element discretizations of elastodynamic port-Hamiltonian systems by using an additive kinem…
