Abstract
Experimental results are presented on the spall strength of PT-3V tita nium alloy and 12Kh18N10T steel as the system size is changed by a fac tor of five. The effects of a 0.5-5% dynamic prestrain and of the dire ction of the load relative to the manufacturing rolling direction on s pall failure were also studied for the titanium alloy. It was establis hed that failure of these metals under high-rate one-dimensional strai n shows significant energy-related size effects. Effects of the rollin g direction and prestrain were less pronounced for the titanium alloy than for steel.
