Effect of Phase-Lags Model on Thermoelastic Interactions of Nonlocal Elastic Hollow Cylinder with Voids Material in the Presence of Time-Dependent Heat Flux

摘要

The analysis of nonlocal cylinder/disk with voids material in the preview of three-phase-lag model of generalized thermoelasticity with time-dependent heat flux has been carried out. The governing partial differential equations are resolved into ordinary differential equations by employing time-harmonic variations. The inner and outer boundary surfaces of the cylinder/disk have been assumed stress free and free from voids concentration. The time-dependent heat flux is applied on the inner boundary of the thermoelastic hollow cylinder along radial direction, and outer surface is considered isothermal. Numerical computations and simulations have been done to analytical results with MATLAB software on PC. Numerically generated data have been presented numerically and graphically for field functions, i.e., temperature, stresses, cubical dilatation, displacement and voids volume fraction against non-dimensional radius. The effect of different models of generalized thermoelasticity with voids material has been represented by computer analyzed results for nonlocal and local elastic materials.
