In this paper, the vibrational and buckling analysis of a cylindrical sandwich panel with an elastic core under thermo-mechanical loadings is investigated. The modeled cylindrical sandwich panel as well as its equations of motions and boundary conditions is derived by Hamilton’s principle and the first-order shear deformation theory (FSDT). For the first time in the present study, various bound...

This study presents methods for treating a kind of nanoclay and investigates the effects of methylaluminoxane (MAO) exposure time and or dodecylamine (DDA) reflux time on in-situ polymerization of ethylene in the presence of nanoclay and examines the morphology and properties of the prepared polyethylene/clay nanocomposites. The results revealed that by increasing MAO exposure time productivity...

Maleic anhydride (MAN) copolymers with methyl methacrylate(MMA), ethyl methacrylate(EMA), methyl acrylate(MA), ethyl acrylate (EA) and buthyl acrylate (BA) ( in a 1:1 mole ratio) were synthesized by free radical polymerizations method under vacuum -azobis(isobutironitrile)(AIBN) as an initiator of reaction at 701C. The copolymer compositions were determined using related 1H NMR spectra techni...

This research was performed to evaluate the mechanical and thermal properties of sugar palm fiber (SPF)- kenaf (KF)-reinforced polypropylene (PP) composites. Sugar palm/kenaf successfully treated by benzoylation treatment. The hybridized bio-composites (PP/SPF/KF) were fabricated with overall 10 weight percentage (wt%) relatively three different fibers ratios between palm-treated kenaf-treated ...

We present a 3D modeling of thermal lensing effect in an edge-pumped trapezoid Yb:YAG/YAG thin disk laser. At first, a Monte-Carlo ray tracing method is used to calculate the absorbed pump power from four sides in such a way that the pump light are totally trapped inside the crystal after total reflections. Secondly, we optimized the absorption efficiency of our laser which is obtained 66.7% wi...
