Acoustic emission in hydrostatic strength tests of spheroplastics

Abstract

Registration of acoustic emission in the process of spheroplastics destruction in a high-pressure hydrostatic chamber is realized. Hardware design does not require specialized equipment and is based on available components. Time synchronization on pressure and acoustic emission graphs ensures pressure fixation of pressures at which the formation of cracks in the spheroplastic sample begins. It is shown that accumulation of destructions begins with pressure, smaller, than pressure fixed as short-term hydrostatic durability.
