... with a relaxation time parameter in the Lord–Shulman (LS) thermoelasticity with the aid of an extended thermodynamics framework. As an application, the newly developed model is applied to a one-dimensional half-space problem which is traction free at one end; a time-dependent thermal shock is imposed at the same...

... and are subjected to membrane tension and intracellular contraction. Implementing the first and second laws of thermodynamics, we derived the fundamental equations that control the self-assembly or growth kinetics of the junction. We predict that the junction may grow or shrink in size depending on the magnitude...

Living cells are enclosed within membranes that are frequently modeled using pure lipid bilayers. Such models may be oversimplifying the complex heterogeneous nature of membranes. In fact...

The transient field equations take mechanical and chemical contributions and microscopic time into account. Either microscopic time or chemical reactions...

..., the dissipation energy during cyclic deformation can be evaluated from a thermodynamics perspective, which offers an approach for the prediction of the fatigue life of highly oriented nanotwins. The cyclic plasticity modeling and fatigue life prediction are unified without additional fatigue damage parameters...

...Rossella Laudani; Martin Ostoja-Starzewski The entropy inequality, commonly taken as an axiom of continuum mechanics, is found to be spontaneously violated in macroscopic granular media undergoing collisional dynamics. The result falls within the fluctuation theorem of nonequilibrium thermodynamics...

It was found that the predictions of the rational energy strength theory were very reasonable compared to the experimental data even if no postulation was taken. Through...

Reddy In this work, we develop a thermo-viscoplasticity model for body-centered cubic (BCC) metals based on a two-temperature theory of nonequilibrium thermodynamics. Modeling the plastic deformation here involves two subsystems, viz., a configurational subsystem...

Then, the thermodynamics of DE was combined to predict the idealized electromechanical softening behavior. Two cases are considered...

Specifically, since two systems are considered in (thermodynamic) equilibrium when they have the same temperature, we show in the case of dynamic buckling that a persistent steady-state difference in kinetic temperature between structure and bath is but indicative of the instability...
