Experimental and computational characterization of the effect of manufacturing-induced defects on high temperature, low-cycle fatigue for MarBN
(Elsevier, 2020-05-22)
Manufacturing-induced defects are a key source of crack initiation and component failure under high temperature cyclic loading. In this work, 3D X-ray micro-computed tomography and microstructural analysis of manufacturing-induced ...
A physically-based high temperature yield strength model for 9Cr steels
(Elsevier, 2018-05-24)
The strength of 9Cr steels, which is controlled by chemical composition and microstructure, evolves significantly under high temperature loading. This paper presents a temperature-independent, physically-based model for ...
A multi-scale crystal plasticity model for cyclic plasticity and low-cycle fatigue in a precipitate-strengthened steel at elevated temperature
(Elsevier, 2016-12-24)
In this paper, a multi-scale crystal plasticity model is presented for cyclic plasticity and low-cycle fatigue in a tempered martensite ferritic steel at elevated temperature. The model explicitly represents the geometry ...
Fatigue damage characterisation of MarBN steel for high temperature flexible operating conditions
(SAGE Publications, 2016-09-10)
This article is concerned with the high temperature low cycle fatigue behaviour of a new nano-strengthened martensiticferritic steel, MarBN. A range of strain-controlled, low cycle fatigue tests are presented on MarBN at ...
Influence of material inhomogeneity on the mechanical response of a tempered martensite steel
(SAGE Publications, 2017-01-13)
Failure in steel weldments operating at high temperatures often occurs in the heat-affected zone adjacent to the weld. Such failures can be a result of material inhomogeneity within the heat-affected zone and in the case ...
