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, ...
In-situ SEM study of fatigue micro-crack initiation and propagation behavior in pre-corroded AA7075-T7651
(Elsevier, 2020-04-18)
Fatigue micro-cracking behavior in pre-corroded AA7075-T7651 is analyzed by in-situ scanning electron microscopy (SEM) observation and SEM-based fractography. The experimental results show that (i) fatigue microcracks ...
Experimental investigation on damage evolution in pre-corroded aluminum alloy 7075-T7651 under fatigue loading
(Elsevier, 2020-09-01)
This paper experimentally investigates the fatigue damage evolution in pre-corroded aluminum alloy (AA) 7075-T7651 via digital image correlation (DIC) and scanning electron microscopy (SEM). Three stages of fatigue damage ...
