Math. 225, 1-17 (2002). Summary: We establish existence and uniqueness of weak solutions to a class of second order distributed parameter systems with sudden changes in the input term. Such systems are often encountered in flexible structures and structure-fluid interaction systems that utilize smart actuators. A Galerkin finite dimensional approximation scheme for computing the solution of these systems is developed and its strong convergence is proved. Numerical results are also presented.For the entire collection see [Zbl 1044.35001].
