Cyclic plasticity of welded P91 material for simple and complex power plant connections
(Elsevier, 2016-02-10)
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 physically-based constitutive model for high temperature microstructural degradation under cyclic deformation
(Elsevier, 2017-03-23)
This paper presents a dislocation-mechanics cyclic viscoplasticity model which incorporates the key physical micro-mechanisms of strengthening and softening for high temperature deformation of 9Cr steels. In particular, ...
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 ...
