摘要：
Abstract— The results of high rate tensile and compact tension fracture toughness tests conducted on BS 4360 ‘A’ grade ship steel are presented. Tensile results are reported for strain rates within the range 10–2–103/s and fracture toughness values at rates of increase of J integral within the range 103–106 N/mm/s. The tensile properties of upper yield, lower yield and UTS are shown to be linearly dependent on the logarithm of strain rate whilst fracture toughness is shown to decrease with increasing loading rate prior to approaching a minimum value. The decrease in fracture toughness with increasing test rate is shown to be related to a change in the micro‐mechanism of fracture. Copyright © 1991, Wiley Blackwell. All rights reserved
