A thermo-chemo-mechanically (TCM) coupled peridynamic (PD) model is proposed to analyze the crack behavior in solids considering heat conduction, species diffusion, and chemical reactions. PD theoretical framework established based on non-equilibrium thermodynamics. The influences of diffusion reactions Helmholtz free energy density subsequent formation propagation cracks are distinguished by i...

Thermoelastic damping (TED) in a circular micro-plate resonator subjected to an electrostatic pressure is studied. The coupled thermo-elastic equations of a capacitive circular micro plate are derived considering hyperbolic heat conduction model and solved by applying Galerkin discretization method. Applying complex-frequency approach to the coupled thermo-elastic equations, TED is obtained for...

Thermo-responsive brush copolymers poly(methyl methacrylate (MMA)-co-2-(2-bromoisobutyryloxy) ethyl methacrylate (BIEM)-graft-(N-isopropyl-acrylamide) (NIPAAm)) were synthesized using Cumediated “living” radical polymerization (LRP) approach. Varied grafting densities of the brushes were obtained through adjusting backbone structure as random, gradient and block respectively. The effect of graf...

In many flow phenomenons of fluid with medium molecular weight, the energy flux is effected due to inhomogeneity concentration mass. This contribution considered as diffusion-thermo effect or Dufour effect. this research article addressed for magnetohydrodynamics (MHD) Jeffrey’s fractional past an exponentially accelerated vertical plate generalized thermal and mass transports through a porous ...

The present study was carried out to investigate the effect of alloying elements and thermo-mechanical treatment (TMT) i.e. hot rolling and forging with different reduction ratios on the hardness (HV) and impact toughness (J) of heat-treated low alloy steels. An understanding of the combined effect of TMT and alloying elements and by measuring hardness, impact toughness, resulting from differen...
