Previous strength determinations of ceramics subject to impulsive loads were interpreted in terms of a theory based on material inertia. Recent experiments are described, which show (1) that the dynamic strengthening mechanism is athermal, as required by the inertial theory, and (2) that microcrack growth, rather than initiation, is suppressed by the inertial effect.
