Spatiotemporal nonlocal behavior of fiber-reinforced thermodiffusive medium with rotation and temperature-dependent properties under three-phase-lag model

Abstract

Purpose This study aims to predict the response in a fiber-reinforced thermodiffusive medium with rotation and temperature-dependent material characteristics on account of mechanical load. A mathematical framework of the governing equations is obtained by using three-phase-lag theory and space–time nonlocal elasticity. Design/methodology/approach An analytical solution of the complex system is obtained using normal mode analysis approach yielding the distributions of the field quantities. Findings Numerical simulations of the theoretical model are performed using MATLAB software and demonstrated in graphical form. A comparative analysis of the results is done to account the effects of various material parameters, followed by some concluding remarks. Originality/value The present research work is original, as it proposes a novel theoretical model which integrates spatiotemporal nonlocal elasticity and thermodiffusion theory with three-phase-lag. Furthermore, a comprehensive analytical–numerical scheme is provided to analyze the fiber-reinforced response in the current scenario with rotation and temperature-dependent properties, which has not been discussed yet in the earlier studies.
