Computerised System for Measuring the Fracture Resistance of Ductile Steels Using the Unloading Compliance Method

摘要

A general purpose computerised system for measuring the fracture resistance of ductile steels using the unloading compliance method is described. The system is capable of controlling the test and analysing the data obtained from compact tension specimens and single edge notch specimens in three-point bend. Simulated tests are described for optimising the number of digitisation points and percentage unloading required to achieve an acceptable accuracy from the data acquisition system. Typical results are presented for an A508 Class II steel and a 1CrMoV steel obtained using a pre-cracked Charpy and a 25 mm compact tension specimen, respectively. (Atomindex citation 15:055664)
