Impact energy evaluation with full-thickness specimens at drop-weight tear test
EDN: NOAYMA
Abstract
The results of instrumented drop-weight tear tests of shipbuilding and pipeline steels with measurement of fracture (absorbed) energy are considered. Ratios are proposed for an assessment of the maximum fracture energy and its changes in presence of separations or cleavage areas in fracture. Introduction of the fracture energy measurement allows to avoid subjectivity of estimates of steels cold resistance based on fracture appearance visual analysis and to obtain data for comparison of pipeline steels in respect of both tendency to brittle fracture and ductile fracture energy.
