Impact Testing
PROPOSAL FOR A NEW METHOD FOR TESTING IMPACT RESPONS
Summary
With impact at high velocity we are often pushing the boundaries of what is physical possible with materials. However, impact response at high velocity is an extremely complicated issue and is not well understood. Impact strength is not a recognized material property. What we do know is that different materials respond differently to impact under different conditions. Therefore, with impact assessment, results from experiment should be conclusive, but we rely heavily on modelling. The reason for this is – bizarre as it may sound – that we have no suitable method available to test and research impact response at high velocity. Over the years, impact science has become largely a theoretical affair. The computer models can, however, not be accurately compared with physical results. This is a major safety concern.
