Response of a novel beam-to-column/brace-to-frame connection to monotonic and cyclic shear loading
, Article Proceedings of the International Conference on Offshore Mechanics and Arctic Engineering - OMAE, 9 June 2008 through 13 June 2008, Berlin ; Volume 2 , 2008 , Pages 609-618 ; 9780791848197 (ISBN) ; England, G.

Abstract
A new universal structural joint was developed. While in bending it has a high rotational capacity, which can be accompanied by large bending stiffness and strength, in shear, it also has a very high shear deformation capacity, which can again be accompanied with large shear stiffness and strength. While the former characteristic makes it a good candidate for being used as a beam-to-column joint, the latter makes it highly applicable in connecting braces of a braced frame to the frame members. The experimental study carried out previously on this joint, concentrated on the performance of its steel specimens under 'monotonie' shear loading as well as that of its aluminium specimens under both...
Coating thickness and roughness effect on stress distribution of A356.0 under thermo-mechanical loadings

Abstract
Cast aluminium-silicon alloy, A356.0, is widely used in automotive components such as diesel engine cylinder heads and also in aerospace industries because of its outstanding mechanical, physical, and casting properties. Thermal barrier coatings are applied to combustion chamber in order to reduce fuel consumption and pollutions and also improve fatigue life of components. However, studies on behaviour of A356.0 with thermal barrier coating are still rare. The purpose of the present work is to simulate stress distribution of A356.0 under thermo-mechanical cyclic loadings, using a two-layer elastic-visco-plastic model of ABAQUS software. The results of stress-strain hysteresis loop are...
