Presenting real an dramatic images, this program explores the forces released by explosions and their impact on materials. It identifies key features of explosions: rapid gas expansion and—with high explosives—shock waves. It also looks at the properties of structural materials, particularly their resistance to being broken apart. It shows how these properties can be measured and used to predict the material’s response to forces. It also shows applications of these ideas in the real world of mining and demolition.
