Abstract

Since the early years of this century, research has been undertaken, both experimentally and theoretically, into the response of concrete to impact loads. Much of this work is still valid today. However, developments in testing equipment - especially for measuring stress and strains at high rates of strain - coupled with increasingly sophisticated mathematical modelling techniques, have led to a continuing improvement in our knowledge and understanding of the behaviour of 'brittle' materials such as concrete. This is particularly so when the material is subjected to high rates of strain and complex levels of confinement. Earlier work has shown that the presence of a sleeve, which confines the concrete during the impact, results in an increase in the load carrying capacity.
