The utilization of explosive loading as a nondestructive evaluation tool in geologic materials (Q675575)

This paper describes the use of a small explosive charge to evaluate geologic material in a non-destructive manner. One-dimensional computations have been performed using the Lagrangian finite difference code WONDY to investigate the effects that open joints and weak layers of unconsolidated material have on the propagation of stress waves resulting from the detonation of an explosive charge. Data from testing conducted by others in models or in full scale in a number of different materials have been collected and examined.
