Abstract
Abstract Aims A computer simulation to show the effects of an explosive device's blast wave and shrapnel injuries to humans. Methods Unity 3D project written in C# with real time physics showing the effects on people and listing probable injuries sustained. Results An explosive mass of 0.1kg to 100kg PTEN can be simulated showing the evolving blast wave and up to 100,000 shrapnel particles. The blast wave can show the maximum overpressure, velocity of the shock front and temperature Video: https://youtu.be/ICH2xHR6678. The shrapnel is simulated with the physics engine including velocity, energy of injury and body/limb hit points to calculate their effect. A model of the Manchester Arena is used as an example. Example blastwave data: Conclusions This novel approach to simulation showcases what is possible with computer simulation. Next steps are verification of data and building of more models. A higher detailed human model is being worked on which includes organs and bones.
