Derivation of the P2T Criterion (in Closed Form) Based on the Frey Shear Band Mechanism

Abstract

We obtain an approximate closed form equation for the critical P2T criterion for explosive initiation based on the shear band theory of explosive initiation. The theory assumes that shock loading of explosives produces a calculable shear velocity resulting in shear band formation. Heating within the shear bands leads to hot spot formation which in turn leads to explosive initiation. An example of the use of the derived equation for Composition-B is given.
