Q

What are the three detonation effects and explain them?

A

Deformation: the surface of an object in direct contact with the charge is crumbled, cratered, depressed or indented from the compressive shock wave.
Spalling: the opposite side of the target is split or a hole is created because of the shock wave moving trough the target and chips away at the tensile strength
Radial Cracking: pressure load on the target will crack and displace material beyond the crater and the spall
