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 ...
Development and assessment of a blade element momentum theory model for high solidity vertical axis tidal turbines
(Elsevier, 2020-01-20)
Tidal energy is an attractive renewable resource given its predictability. The production of reliable, efficient and cost-effective tidal energy turbines requires the development of computer models for assessment and design ...
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 ...
Thermomechanical modelling for the linear friction welding process of Ni-based superalloy and verification
(SAGE Publications, 2020-01-22)
This paper presents a fully coupled thermomechanical model for the linear friction welding process of Inconel-718 nickel-based superalloy by using the finite element method. Friction heat, plastic work, and contact formulation ...
