An investigation was conducted to determine the ratio of dynamic to static yield strengths of four metal alloys having different crystallographic and metallographic structures. Thick-wall cylindrical tube specimens were hydrostatically loaded at low and high rates of strain to obtain circumferential yielding. The ratios on the inside and on the outside diameters of the specimens for the four materials investigated were as follows stainless steel FCC, 1.03 and 1.005 4340 steel BCC, 1.06 and 1.09 alpha titanium HCP, 1.12 and 1.09 beta titanium BCC, 1.26 and 1.29. Test procedure is given and results are discussed. Author
