The paper presents a computational study for design of experimental configurations that may permit the recovery of weak-shock loaded high-strength brittle ceramics such as silicon carbide with controlled amounts of damage. A set of 8 configurations involving momentum traps, and subjected to a nominal shock pressure of 4 GPa, is analyzed using finite element analysis with linear elastic and damage material models. The analyses identify influences of: (i) introducing a hole in the specimen center (ii) specimen size, and (iii) impedance graded trapping.
