Analysis of energy flow in thick plate structures
(Pergamon-Elsevier Science Ltd, 1997)At sufficiently high frequencies: where the structural wavelength is much smaller than the thickness of the structure, the rotational inertia and transverse shear effects become increasingly important. In this study the ... -
Analysis of orthotropic plate structures by the direct-dynamic stiffness method
(Pergamon-Elsevier Science Ltd, 1995)… -
Analytical and finite element comparisons of stress intensity factors of composite materials
(Elsevier Sci Ltd, 2000)In this paper, a comparative study regarding the determination of stress intensity factors (SIF) for non-standard thin composite plates is presented. Carbon-epoxy composite plates are considered for the study. Unnotched ... -
Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ... -
Artificial neural network analysis of heat pumps using refrigerant mixtures
(Pergamon-Elsevier Science Ltd, 2004)In this study, we have investigated the performance of a vapor compression heat pump with different ratios of R12/R22 refrigerant mixtures using artificial neural networks (ANN). Experimental studies were completed to ... -
An assessment of the effects of in-plane vibrations on the energy flow between coupled plates
(Academic Press Ltd, 1996)The majority of the studies of energy transmission in plate-type structures are based on the assumption that the main component of the energy transfer is due to flexural waves, and the contribution of in-plane waves may ... -
Clamp fixation to prevent unfolding of a suture knot decreases tensile strength of polypropylene sutures
(Springer, 2012)Purpose Although sutures evolved in last decade and the product spectrum broadened largely, they can be still classified into two: monofilament and multifilament. Sutures are the mainstay of orthopedic procedures like ... -
A comparative study of lubricated friction and wear behaviour of Al-25Zn-3Cu-3Si bearing alloy
(Sage Publications Ltd, 2014)Lubricated friction and wear behaviour of Al-25Zn-3Cu-3Si alloy was investigated on a block-on-disc test machine in comparison with 60/40 brass and SAE 65 bronze. T6 heat treatment increased the hardness, strength and wear ... -
A comparative study on cutting tool performance in end milling of AISI D3 tool steel
(Elsevier Science Sa, 2005)In this work, high speed end milling of AISI D3 cold-work tool steel hardened to 35 HRC was investigated using coated carbide, coated cermet, alumina (Al2O3) based mixed ceramic and cubic boron nitride (CBN) cutting tools. ... -
Computational Fluid Dynamics Investigation of Brush Seal Leakage Performance Depending on Geometric Dimensions and Operating Conditions
(Asme, 2016)Brush seals require custom design and tailoring due to their behavior driven by flow dynamic, which has many interacting design parameters, as well as their location in challenging regions of turbomachinery. Therefore, ... -
Computational Fluid Dynamics Investigation of Labyrinth Seal Leakage Performance Depending on Mushroom-Shaped Tooth Wear
(Asme, 2016)Conventional labyrinth seal applications in turbomachinery encounter a permanent teeth tip damage and wear during transitional operations. This is the dominant issue that causes unpredictable seal leakage performance ... -
Computer aided modelling of flexible forming process
(Elsevier Science Sa, 2004)Flexible forming enables the production of sheet metal parts with complex contours and bends by utilising a flexible medium, such as natural or synthetic rubber, as one half of a conventional die set. This study is concerned ... -
A computer simulation for estimating lower bound fracture strength of composites using Weibull distribution
(Elsevier Sci Ltd, 2004)Estimating confidence lower bound for fracture strength of composites is a key concern in design and manufacture, and the Weibull distribution has been widely used for this purpose. Previous simulation-based studies presented ... -
