The paper presents an experimental investigation of the mechanical behavior of specimens made of alumina ceramics prior to catastrophic fracture and the transition to the blow-up mode. Ceramic specimens are tested in three point bending and uniaxial compression tests. The surface velocity of the loaded specimens is registered using a laser Doppler vibrometer. The duration of the stage of a catastrophic increase in the lateral surface velocity prior to fracture is approximately half a millisecond in three-point bending tests and about 0.1 ms in compression tests.
