The use of intelligent nanocomposites in sensing and actuation applications has become quite common over the past decade. In this article, electro-thermo-mechanical nonlinear dynamic buckling of an orthotropic piezoelectric nanocomposite (PNC) cylindrical shell conveying viscous fluid is investigated. The composite cylindrical shell is made from Polyvinylidene Fluoride (PVDF) and reinforced by ...

Abstract In the present research, a numerical modeling approach of initial stage consolidation during spark plasma sintering on microscopic scale is presented. The solution fully coupled thermo-electro-mechanical problem also accounting for grain boundary and surface diffusion found by using staggered way. finite-element method applied solving while finite-difference problem. A Lagrange-based n...

Novel mixed antioxidants composed of antioxidant IPPD and lanthanum (La) complex were added as a filler to form natural rubber (NR) composites. By mechanical testing, Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) and thermogravimetric analysis (TGA), a string of data, including the mechanical properties, the variation of internal groups and the thermal and...

In the work presented in this contribution we have investigated the reduction of dynamical thermo-mechanical systems and we propose a new reduction method that can be seen as an extension of the common Craig-Bampton method [2] where multiphysics is now implicitly included in the projection basis. The efficiency of this new approach has been evaluated in multiple configuration of a representativ...

Optical forces in guided-wave nanostructures have recently been proposed as an effective means of mechanically actuating and tuning optical components. In this work, we study the properties of a photonic crystal optomechanical cavity consisting of a pair of patterned Si3N4 nanobeams. Internal stresses in the stoichiometric Si3N4 thin-film are used to produce inter-beam slot-gaps ranging from 56...
