Overview

The shock and impact behaviour of structures is an extremely challenging area. It is therefore important to utilize the contributions emerging from theoretical, numerical and experimental studies on structures, as well as investigations into material properties under dynamic loading conditions. Reflecting the broad range of research work currently being carried out in academia and industry, this book contains the proceedings of the Eighth International Conference on Structures Under Shock and Impact. The papers included will be of interest to engineers from military, nuclear, aeronautical, transportation and other backgrounds, who are actively involved in this area.
