Damage Assessment of Similar Martensitic Welds Under Creep, Fatigue and Creep-Fatigue Loading

Volume 6: Materials and Fabrication, 2020
Abstract For the assessment of welds under high-temperature conditions in the creep or creep-fatigue regimes, the knowledge on the damage location and its temporal evolution are of high importance. The failure behavior of similar welds of ferritic-martensitic steels in the creep regime is well known.

High temperature creep, fatigue and creep–fatigue interaction in engineering materials

International Journal of Pressure Vessels and Piping, 2001
Abstract An attempt has been made to systematize the criterion for the crack initiation, the crack growth and the final fracture in creep, fatigue and creep–fatigue interaction conditions at high temperatures. Reference has been made to the systematically designed studies performed hitherto by the authors and colleagues, including the comparative ...

Multiaxial creep-fatigue rules

Nuclear Engineering and Design, 1995
Abstract Within the UK, a comprehensive procedure, called R5, is used to assess the high temperature response of structures. One part of R5 deals with creep–fatigue initiation, and in this paper we describe developments in this part of R5 to cover multiaxial stress states.

Modeling Creep Fatigue

2009
Abstract The overarching goal of life-prediction research is to develop models for the various types of time dependencies in the crack-tip damage accumulation that occur in materials subjected to elevated temperatures. This article focuses on describing the models based on creep, oxidation kinetics, evolution of crack-tip stress fields ...
