Dynamic Fracture Toughness Determined from Instrumented Pre-Cracked Charpy Tests.
Abstract
The use of an instrumented impact hammer on pre-cracked Charpy V-notch specimens led to a reliable and inexpensive method for determining dynamic fracture toughness. Measurements were made on A-533, Grade B, Class 1 steel from -125F to +75F. The data were found to be in excellent agreement with those obtained by other workers on much larger specimens. Similar tests were run with standard Charpy V-notch specimens to determine dynamic tensile yield strength values. A comparison of the dynamic yield and toughness values suggests a meaningful technique for estimating the NDT temperature, which should be of practical value in nuclear reactor surveillance programs.
