in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...

This article is a study of the research development electrodynamic phenomena occurring in ultra-fast drives. These types linear drives are among fastest, not only because huge accelerations achieved, but, above all, extremely short reaction time. For this reason, used hybrid short-circuit breakers. The type drive actually magneto-thermo-elastic nature, but coupling these should be considered we...

Nowadays, shape memory polymers (SMPs)-based devices are required to be much smarter produce large recovery and force with lower working temperatures in order enable multi-functionality them. They could play a vital role the advancement of multi-functional soft robot manipulators, biomedical tools wearable where is key challenge must around body temperature, or sustainable smart systems low ene...

A novel magneto-active gel based nanomaterial system is presented to provide precise control of temperature to a localized area in response to externally controlled magnetic stimuli. Integration of ferromagnetic nanoparticles (Fe3O4) in the polyethylene glycol (PEG) based thermo-responsive polymer provides the swelling and de-swelling behavior of magnetic stimuli controlled system by generating...

The influence of multi-cracking on the magnetic response more (Co) or less (Ni78Fe22) magnetostrictive ferromagnetic nanofilms flexible substrates has been studied by combining tensile tests with in situ magneto-optical Kerr effect magnetometry measurements, up to large strain (20%). results show that variations features are significant elastic domain (before cracking), while they slightly affe...

A typical operating temperature of a solid oxide fuel cell (SOFC) is quite high above 750 °C and affects the thermomechanical behavior of the cell. Thermal stresses may cause microstructural instability and sub-critical cracking. Therefore, a joint analysis by the computational fluid dynamics (CFD) and computational structural mechanics based on the finite element method (FEM) was carried out t...
