A numerical method previously described for predicting large dynamic and permanent deformations of twodimensional structures of elastic-plastic material was extended to analyze explosively-loaded unbonded concentric rings. This extension was employed to carry out comparisons between predicted and measured dynamic responses and permanent deformations of explosivelyloaded unbonded concentric 6061-T6 rings. Good agreement between theory and experiment was found. Author
