Сущностный анализ технологий разрушения твердых тел

Abstract

The problem matter is defined as deformation of materials beyond its elasticity limit, another word destruction of integrity of same. Any destruction is a very fast flowing process. An initially integral material during such process looses internal ties and forms empty spaces within its body. The theory of destruction by Griffith is well applicable to a phenomena where one fracture is formed as the result of an impact, another word in an ideally fragile material. But to vast majority of materials this theory does not apply. Destruction of materials passes through period of plastic deformations, as well as inner-particle shifting deformation within the mass of material. In this case destruction of material occurs not as of large macro fractures but rather large number of microscopic fractures that form large number of micro pores. Lab tests, as well as other kinds of practical experience, confirms that short term but strong impacts, such as striking, lead to high efficiency of such material destruction.
