Abstract
Hollow circular cylinders of single crystal copper are subjected to ex ternally applied explosive loads that cause the collapse of the cylind er. Then numerical simulations are performed to understand the deforma tion process that leads to localized deformation and tensile cracking, observed in partially collapsed cylinders of fee single crystals. The results of experiments and numerical simulations are in good agreemen t. (C) 1998 Published by Elsevier Science S.A. All rights reserved.
