Abstract :
Hollow circular cylinders of single crystal copper are subjected to externally applied explosive loads that cause the collapse of the cylinder. Then numerical simulations are performed to understand the deformation process that leads to localized deformation and tensile cracking, observed in partially collapsed cylinders of fcc single crystals. The results of experiments and numerical simulations are in good agreement.
