Scatter in Charpy Data Considered as a Transferrable Parameter

August 29, 2019

Charpy V-notch (CVN) impact tests are the most widely used method for characterizing material toughness in steel applications. While the CVN method is both cost-effective and efficient, CVN data is limited when it comes to performing fitness-for-service or remaining-life calculations. Correlated data between Charpy and other fracture tests are used together for these purposes, but this is also a limited solution, especially in modern steel applications.

EWI has developed as assessment method that can characterize the ductile-to-brittle temperature transition behavior for structural steels more reliably than other existing methods. The approach can be applied to a wide range of modern steels including structural pipeline and marine materials.

Bill Mohr, Principal Engineer for Structural Integrity, has written a new paper, Scatter in Charpy Data Considered as a Transferrable Parameter, to discuss this new scatter assessment method and its future applications.
