Coherent structures at different contraction ratios caused by two spill-through abutments
(Informa UK Limited, 2017-8-23)
Detached eddy simulation (DES) at a channel Reynolds number of 45,000 is used to investigate the coherent structures forming around spill-through abutments located at opposite sides of a rectangular channel which contract ...
Design weight of armour stone considering the effect of extreme waves
(Elsevier BV, 2008-3)
In this study, waves with the heights higher than H-1/3 in an irregular wave train are called as extreme waves and defined with the help of extreme wave parameter, alpha(extreme). In order to see the effect of extreme waves ...
Flow and turbulence structure around a spur dike in a channel with a large scour hole
(American Geophysical Union (AGU), 2011-12)
The flow and turbulence structure around a vertical-wall spur dike that extends over the whole depth of a straight channel are investigated using detached eddy simulation (DES). The channel Reynolds number in DES and the ...
Vibration of beams with multiple open cracks subjected to axial force
(Elsevier BV, 2005-10)
A new method is proposed to obtain the eigenfrequencies and mode shapes of beams containing multiple cracks and subjected to axial force. Cracks are assumed to introduce local flexibility changes and are modeled as rotational ...
Atrial and ventricular fibrillation: computational simulation of spiral waves in cardiac tissue
(Springer Science and Business Media LLC, 2009-10-25)
This manuscript proposes a novel, efficient finite element solution technique for the computational simulation of cardiac electrophysiology. We apply a two-parameter model that is characterized through a fast action potential ...
A computational model for reinforced concrete members confined with fiber reinforced polymer lamina: Implementation and experimental validation
(Elsevier BV, 2007-7)
This study presents a computational model to simulate the behavior of confined concrete in column plastic hinge zones. The model describes the distribution of confining stresses within a circular column cross-section and ...
Repair and strengthening of reinforced concrete columns with CFRPs
(SAGE Publications, 2010-8-17)
In this study, seismic retrofitting of undamaged and moderately damaged RC columns with CFRP was investigated. The experimental program was conducted on five RC columns with inadequate tie spacing, 90-degree hooks at tie ...
