Shock and impact on structures

There is considerable practical interest in the resistance of structures to impact and shock effects generally from a variety of sources. Applications range from the high speed impact of birdstrikes in aeroengines to soft impact loads on concrete structures. This book aims to show the current state of research and experiment on several shock and impact studies, by leading scientists in the field. They have each prepared separate contributions covering a broad range of topics, as follows: Chapter 1, by J. A. Zukas, deals with the modelling of fast transient loads on structures. The second chapter, by A. Barbagelata and M. Primavori, provides a state of the art analysis of blast waves impinging on surface structures. In the next chapter N. Jones examines the perforation of metal plates under projectiles with low impact velocity. Chapter 4 by Z. Rosenberg deals with the dynamic response of ceramics to shock wave loading, and Chapter 5 by A. Miyamoto and M. W. King studies the behaviour of reinforced concrete slabs under soft impact loading. C. Ruiz and D. Hughes in Chapter 6 describe impact problems in aeroengines, including the cases of hard and soft impact. Chapter 7, by S. Cescotto and Y. Y. Zhu, discusses the use of a type of finite elements to reproduce contact problems, including Coulomb dry friction law, and numerical results are presented for dynamic analysis. The last chapter by J. Marti studies the problem of impact on transport flasks. This is a problem of great importance in highly radioactive materials, and the various engineering and licencing requirements on transport and storage of flasks are reviewed.
