Corrosion damage evolution of the aircraft aluminum alloy 2024 T3
(2016)Purpose - The purpose of this paper is to quantify the corrosion damage evolution that has occurred on the aircraft aluminum alloy 2024 after the exposure to Exfoliation Corrosion Test (EXCO) solution. Moreover, the effect ... -
Failure analysis of an aluminum extrusion aircraft wing component
(2016)Purpose - The purpose of this paper is to deal with the failure analysis of a fractured spar stiffener, extruded from 7075-T6 aluminum alloy, which was found in the central wing, trailing edge structure of a military ... -
Fatigue and fracture behavior of pearlitic Grade 900A steel used in railway applications
(2016)In overloaded railway networks, rail surface defects developed under rolling contact fatigue (RCF) if left untreated, may propagate to the bulk of the rail and become critical for its structural integrity. To avoid critical ... -
Fatigue crack growth assessment of corroded aluminum alloys
(2009)The fatigue crack growth behaviour of pre-corroded aluminum alloy has been investigated analytically. For this purpose the fatigue crack growth LTSM-F model has been implemented and upgraded to account for the local material ... -
Fatigue resistance of welded steel tubular X-joints
(2020)High-cycle fatigue experiments are performed on welded tubular steel X-joints, with braces and chord of equal diameter. They are scaled-down joints, used extensively in offshore wind platforms. Three different welding ... -
Finite element methods for piezoelectricity and flexoelectricity with fracture mechanics applications
(2017)Flexoelectricity is the coupling of polarization to strain gradients. This effect is size-dependent and is most prominent in nanoscale structures in which gradients are large. In our previous work, we have established a ... -
Fracture behavior of bimetallic Al-Cu LBW joints
(2013)Pulsed laser spot welding of copper tubing to aluminum sheet is currently used for the construction of solar thermal absorbers. The bimetallic joints should withstand high thermal stresses during the operation of the ... -
High-performance medical-grade resin radically reinforced with cellulose nanofibers for 3D printing
(2022)The effect of Cellulose NanoFiber (CNF) addition to a medical-grade resin in Stereolithography (SLA) Additive Manufacturing (AM) technology is reported, aiming to elaborate an easily processable, highly stiff bio-compound. ... -
Low Cycle Fatigue Behavior of Plastically Pre-Strained HSLA S355MC and S460MC Steels
(2022)Cold roll forming used in the manufacturing of lightweight steel profiles for racking storage systems is associated with localized, non-uniform plastic deformations in the corner sections of the profiles, which act as ... -
Mechanical performance of laser spot-welded joints in Al-Al/Cu solar thermal absorbers
(2018)The mechanical performance of laser spot welded joints used in Al-Cu and Al-Al thermal absorber systems has been evaluated under different laser welding and mechanical loading conditions. In the experimental investigation, ... -
Non-local criteria for the borehole problem: Gradient Elasticity versus Finite Fracture Mechanics
(2022)Two nonlocal approaches are applied to the borehole geometry, herein simply modelled as a circular hole in an infinite elastic medium, subjected to remote biaxial loading and/or internal pressure. The former approach lies ... -
Plane asymptotic crack-tip solutions in gradient elasticity
(2009)An asymptotic crack-tip solution under conditions of plane strain is developed for a material that obeys a special form of linear isotropic strain gradient elasticity. In particular, an elastic constitutive equation of the ...
