Original abstract
A large group of relatively cheap particle composites, that consist of brittle matrix and dispersion of plastic (shapable) particles has very different mechanical properties in pull and pressure area of loading. Technical ceramic materials prove some importantly better mechanical qualities in comparison with highly firm steels (rigidity, abrasive wear, high pressure firmness). These materials are often used in technical equipment where the decisive loading is pressure quasi static, ev. repeated cyclic loading. At present, very little is known about micromechanics of damage of these materials, especially by operating of cyclic pressure loading. The reason is very difficult experimental identification of the development of damage of materials loaded in this way. In this contribution are presented our experience with the technology of acoustic emission by watching of the development of damage in ceramic material subjected to cyclic pressure loading by low frequency of loading.
