Description

The damage in the 'spall plane' of tantalum incipiently spalled in a gas gun or from HE loading consists of voids and/or regions of localized shear through which a long, continuous path can be traced. The geometry of this path has been analyzed using wavelets to show that it constitutes an affine fractal with a well defined 'roughness', i. e it scales statistically with the scaling factor in the shock direction being a power of the transverse scaling factor
