Radial displacement behavior Table B-6 summarizes the along length of Group 3 cylinders having t/D^ = and simple ultimate radial displacements and support at a pressure load of ,n,. calculated strains. It is interesting to note that although w, is typi- cally several times the magnitude of w , the calculated strains e and s, are nearly equal. At implosion m m b J ^ f the strains at the flat-spot location on the inside wall experienced slight tension while on the outside wall strains were on the order of 4,000 compression. 69.
