An Introduction to the Development and Use of the Master Curve Method (ASTM Manual) (Astm Manual Series, Mnl 52)
An Introduction to the Development and Use of the Master Curve Method - ASTM Manual - Astm Manual Series, Mnl 52 Author:D. E. McCabe; J. G. Merkle; K. Wallin This new ASTM manual introduces the concept of the Master Curve Method so it can be understood and used by engineers who have had limited exposure to elastic-plastic fracture mechanics and/or advanced statistical methods. It addresses the practical design-related problem of defining the ductile-to-brittle fracture transition temperature of struc... more »tural steels directly in terms of fracture mechanics data. Topics cover: ? Background and historical aspects ? Data validity requirements imposed on test data, and the number of data required to constitute a statistically useable data set for determining a reference temperature, To ? Test specimens that can be used to develop valid KJc ? Fixturing and test equipment needs ? Preparation of specimens (precracking and side-grooving) for testing ? Test machines, their mode of operation, and recommended specimen loading rates ? All of the information needed to calculate values of KJc ? Scale parameter statistical equations for material testing ? Second option for calculating the To temperature that is useable when KJc data have been generated at various test temperatures ? How the variability of KJc values is handled using the three-parameter Weibull model ? Information on concepts under study ? Brief discussion of important considerations involved in directly applying Master Curve fracture toughness data to the fracture-safety analysis of actual structures« less
