In the present work, the effect of local and inclined loads on plane waves in a fiber-reinforced visco-thermoelastic solid will be investigated in the context of the dual-phase-lag model. The problem is solved numerically by the method of normal mode analysis. Numerical results for thermal temperature, displacement components, and stress are plotted and analyzed. Graphical results show that the effects of the angle of inclination and the nonlocal parameter are evident. Variations in these quantities are plotted in the context of the dual-phase-lag model with isolated boundaries to show the effects of nonlocal parameters and angle of inclination on wave propagation in the fiber-reinforced visco-thermoelastic solid. Compute the physical fields with suitable boundary conditions and perform numerical calculations using MATLAB programming. It was found that the inclined load plays a significant role in the distribution of all the physical quantities. The local parameter has a strong influence on the variation of all the physical quantities. The boundary conditions are met by all physical quantities.
