FRACTURES PRODUCED BY STRESS PULSES IN GLASS-LIKE SOLIDS
Abstract
Measurements have been made of the amplitudes of the maximum tensile stress pulses which could propagate along rods of glass and of two glass-like plastics (polystyrene and polymethylmethacrylate) without producing fracture. Small quantities of explosive were detonated at one end of the rod so that a compression pulse travelled down the rod and on reflection at the opposite end returned as a tension pulse. The displacement-time curve of the free end was recorded with a condenser-microphone arrangment and the stress was obtained by differentiating this curve numerically. The maximum amplitudes were compared with the tensile strength of the specimen as measured in a standard tensile testing machine. (Author-PL).
