Analysis of heat affected zone in welded aluminum alloys using inverse and direct modeling
(2008)The concept of constructing parameter spaces for process control and the prediction of properties within the heat affected zone (HAZ) of welds using inverse modeling is examined. These parameter spaces can be, in principle, ... -
Computational kinetics simulation of the dissolution and coarsening in the HAZ during laser welding of 6061-T6 Al-alloy
(2007)Laser beam welding (LBW) has become common practice in the production lines of several industrial sectors including the electronics, domestic appliances, and automotive industries. The advantages of LBW over conventional ... -
Effects of temper condition and corrosion on the fatigue performance of a laser-welded Al-Cu-Mg-Ag (2139) alloy
(2010)The effects of temper condition and corrosion on the fatigue behavior of a laser beam welded Al-Cu-Mg-Ag alloy (2139) have been investigated. Natural aging (T3 temper) and artificial aging (T8 temper) have been applied ... -
Improvement of fatigue crack growth resistance by controlled overaging in 2024-T3 aluminium alloy
(2014)A controlled overaging process is proposed to increase region II fatigue crack propagation resistance of 2024-T3 aluminium alloy. Overaging was achieved by subjecting the material from the initial T3 state to heat treatment ... -
Influence of nano-inclusions' grain boundaries on crack propagation modes in materials
(2011)The effect of nano-inclusions on materials strength and toughness has attracted great interest in recent years. It has been shown that tuning the morphological and microstructural features of materials can tailor their ... -
Investigation of the effect of biodiesel blends on the performance of a fuel additive-assisted diesel filter system
(2014)The results of full-scale regeneration tests with a unit silicon carbide diesel particulate filter installed on a single-cylinder diesel engine are presented. Two sets of transient regeneration experiments, one for each ... -
Porous metals with developing anisotropy: Constitutive models, computational issues and applications to deformation processing
(2000)A constitutive model for a porous metal subjected to general three-dimensional finite deformations is presented. The model takes into account the evolution of porosity and the development of anisotropy due to changes in ... -
Structural analysis using a dipolar elastic Timoshenko beam
(2013)In recent years, several non-local beam theories have emerged in trying to model stiffness and strength phenomena observed in micro-beams used in micro-mechanical systems (MEMS) and sensors. Of particular importance are ... -
Tensile and fatigue behaviour of wrought magnesium alloys AZ31 and AZ61
(2008)The mechanical behaviour of two hot rolled magnesium alloys, namely the AZ31 and AZ61, has been evaluated experimentally under both monotonic and cyclic loading. Both longitudinal (L) and long transverse (LT) directions ...
