Description

---

In this book, a new phenomenological approach to brittle medium fractu re initiation under shock pulses is developed. It provides an opportun ity to estimate fracture of media with and without macrodefects. A qua litative explanation is thus obtained for a number of principally impo rtant effects of high-speed dynamic fracture that cannot be clarified within the framework of previous approaches. It is possible to apply t his new strategy to resolve applied problems of disintegration, erosio n, and dynamic strength determination of structural materials. Special ists can use the methods described to determine critical characteristi cs of dynamic strength and optimal effective fracture conditions for r igid bodies. This book can also be used as a special educational cours e on deformation of materials and constructions, and fracture mechanic's.
