| Description | New numerical methods developed for predicting the macroscopic behaviour of ceramics during impacts on the basis of microscopic characteristics that actually determine the response in service. New methods of measuring the mechanics of microscopic features for input into the models developed. Comparison of the different armour materials available on the above basis suggests that differences in microscopic distribution of defects are responsible for different behaviour in defeating projectiles. |
| Exploitation Route | Much of this work is proof of concept. It can now be taken forward to develop modelling tools which will: 1. Enable the design of armour to defeat specific threats. 2. Enable the production of new materials which will enhance the capabilities of the armour. |

| Description | The findings are being used in continued research by the MoD and Universities in understanding and predicting the performance of ceramic armour. This is being explored in one of the follow-on research projects entered. |
