THEORETICAL CALCULATIONS OF THE SRESSED-DEFORMED STATE OF POWDER MATERIALS

摘要

The report describes the results of investigations dedicated to the study of disturbance growth processes occurred in powder material as a result of rapidly changed effect caused by the explosive loading. This process encompasses a multitude of complex phenomena and according to the loading intensity level every researcher faces the necessity of choosing one of two alternative theories: the elasticity theory and the hydrodynamic theory. The analysis shows that the intensive shift deformations engender the problem linked with a value and proportion of normal and tangent stresses' components. This problem particularly concerns the materials treatment by the sliding front edge of the detonation wave. The report presents as well the results of calculations of the stress components of some porous materials under shock loading that evenly is being spread with a constant rate at the boundary safety ampoule -sample.
