PREDICTION OF THE THEORETICAL BEHAVIOR AND ENERGY TRANSFER WHEN SOLIDS ARE SUBJECTED TO EXPLOSIVE LOADING

Abstract

A technique to describe the mode of fragmentation and the vector velocity of the fragments from a center initiated cylindrical charge has been proposed in this program. The approach taken permits a determination of these variables from the shape of the case at the instant of breakup. The determination of the shape of the cylinder at various increments of time has been obtained by solving the equations of motion for an explosively loaded cylindrical wall. From the shape of the wall both radial and longitudinal strains can be obtained and a probabilistic method for determining fragment size and number is presented. By considering both the shape and acceleration of the wall at the moment of breakup, a method for obtaining the velocity and direction of the fragments is proposed. A brief review and discussion of past developments for theoretical and empirical determinations of fragmentation characteristics which include fragment size, number, distribution, and velocity is also presented.
