In this paper, two-variable refined plate theory and strain gradient (SGT) are adopted termed (TV-SGT) for buckling analysis of moderately thick microplate. The TV-SGT embraces both shear micro-effects simultaneously and, therefore, does not need the correction factor. Notably, governing equations new boundary conditions derived using variational approach. Moreover, generalized complicated prob...

We investigate the possibility of designing phononic crystal-based devices for telecommunication applications using materials commonly employed in microfabrication. We focus our attention on a phononic crystal made of a square array of cylindrical holes drilled in an active piezoelectric PZT5A matrix. Two different structures are considered, namely, a freestanding phononic crystal plate and a p...

In the current workflow and heat exchange of a Casson nanoliquid across penetrable media above moving plate with variable thermal conductivity, adaptive thickness chemical reaction are analyzed. First, governing nonlinear equations partial derivative terms proper extreme conditions changed into ordinary suitable similarity conversions. Then resulting worked out using Keller box method. The effe...

The realization that Earth may have lost heat more slowly in the past than at present has motivated the search for mechanisms to reduce the efficiency of plate tectonics in the past. Several mechanisms have been proposed, such as the resistance to subduction of thick plates (1) produced by deeper melting at higher mantle temperatures (2). We (3) proposed an alternative mechanism, namely subduct...
