The extraordinary properties of graphene nanoplatelets (GPLs) have attracted great attention in the thermomechanical behaviors. Additionally, thermoelastic damping (TED), as a dominant intrinsic dissipation mechanism, is major challenge optimizing high-performance micro/nano-resonators. However, classical TED models fail to explain behavior considering influences small-scale effect and memory-dependent effect. To fill these gaps, present study aims investigate analysis functionally graded...
Abstract Pantograph-OCS system sliding electrical contact is the only way for train energy transmission, which determines safety and stability of transfer. And current-carrying wear core factor that affecting service performance C-Cu pairs. mate pairs often work a long time in rainy/humid environments due to its exposed nature work, interface accumulates large amount water. Existing operating experience has shown carbon plate pantograph experiences abnormal frequent failure during rainfall,...
Functionally graded (FG) sandwich microstructures/nanostructures stand as one of the most promising composite structures due to capability resist thermal shock and high noise in extreme environments. Meanwhile, accurately prediction quality-factor based on thermoelastic damping (TED) is great significance for design high-performance microresonators /nanoresonators. However, classical TED models fail explain size-dependent thermo-mechanical behavior. The nonlocal elasticity surface are...
Based on the generalized thermoelastic diffusion theory with fractional order derivative, dynamic response of an infinite medium a spherical cavity is investigated. The and diffusive properties are assumed to be temperature-dependent, subjected thermal shock chemical potential at inner surface simultaneously. governing equations problem formulated then solved by Laplace transform together its numerical inversion. distributions non-dimensional temperature, displacement, radial stress,...
For nano/micro-scale structures, the classical continuum mechanics can't properly depict size-dependent effect arising in them anymore. In addition, Fourier's law is limited describing heat transfer process nano/microstructures due to its nature of predicting infinite speed. To amend such defects, non-classical based on nonlocal elasticity theory and modified couple stress incorporating non-Fourier model with memory-dependent formulated characterize thermoelastic behaviors micro/nano-scale...
Functionally graded (FG) sandwich structures stand as one of the most representative composite owing to thermal resistance and energy absorption property in non-unfiorm environment. Additionally, accurately estimating thermoelastic damping (TED) is great importance for design high-performance micro/nano-resonators. Nevertheless, classical TED models fail on micro/nano-scale due without considering influences spatial size-dependent effects related heat transfer elastic deformation. The...
In this work, we consider the problem for an infinite medium with a spherical cavity on temperature-dependent properties subjected to stress shock and thermal under fractional-order theory of generalized thermoelasticity. The modulus elasticity coefficient conductivity are taken as linear function temperature. governing equations formulated then solved by Laplace transform together its numerical inversion. nondimensional temperature, displacement, radial stress, hoop obtained illustrated...
