Explosive fragmentation criteria and velocities for vesicular magma

Abstract:

We present a new criterion for primary fragmentation of natural rock samples in shock-tube experiments, and new formulae for the effective strength of natural rock samples, for the size of primary fragments, and for fragmentation velocities. These formulae and the fragmentation criterion are given in terms of the physical properties of the rock and in terms of experimental parameters. The formulae and criterion are derived from numerical solutions and asymptotic analytic solutions to a novel ...
