Introduction
The team interacts actively with research groups spanning several departments within the University of Oxford and at other universities worldwide and maintains strong links with industry and government agencies thus providing unique conditions for cross-fertilisation of ideas in the research field of Impact Engineering.

Objectives
-
to provide experimental data on impact phenomena (focus on constitutive material behaviour at high rates of strain)
-
to provide numerical tools for predictive modelling of materials and structures subjected to impact loading
-
to provide guidelines for design of components and structures threatened by impact loading
