The effect of inclusions on the high‐temperature low‐cycle fatigue performance of cast MarBN: Experimental characterisation and computational modelling
The presence of inclusions is a known source of crack initiation and component failure in cast materials. In this work, the role of inclusions is investigated via a combined program of high-temperature low-cycle fatigue ...
Microstructure modeling of high-temperature microcrack initiation and evolution in a welded 9Cr martensitic steel
(SAGE Publications, 2019-02-28)
Welded joints in tempered 9Cr-1Mo operating at elevated temperatures are well known to be prone to premature failure due to cracking in the heat-affected zone. This paper describes a crystal plasticity model to predict the ...
Cyclic plasticity of welded P91 material for simple and complex power plant connections
This paper focuses on with the cyclic plasticity modelling of welded, ex-service P91 material. A multi material model is developed for high temperature cyclic plasticity, including the effects of the three different material ...
A through-process, thermomechanical model for predicting welding-induced microstructure evolution and post-weld high-temperature fatigue response
This paper is concerned with the development of a modelling framework to predict the effects of welding and post-weld heat treatment on thereto-mechanical performance of welded material, as a step towards a design tool for ...
