Piezoelectric stress transducer used for measurements of explosions in hard rock
Abstract
Piezoelectric transducers were considered for measuring the explosion stress waves in hard rocks. The transducers uses to crystal plates which have the good features of high stiffness, high water tightness and simple manufacturing technique, etc., for assembling the structure and the riveting technique. Examples of part of the test results are given.
