Abstract

This study investigates the dynamic behaviour of nonlocal thermoelastic solid with diffusion subjected to thermal source, with a focus on the influence of angular frequency on the material. To examine this we consider nonlocal thermoelastic solid with diffusion. The governing equations are solved in the frequency domain to analyse the frequency-dependent response of the nonlocal thermoelastic solids with diffusion. Our findings are that angular frequency significantly effects the normal stress, shear stress, mass concentration and temperature change. The study highlights the importance of angular frequency in determining the stress, temperature and concentration fields in nonlocal thermoelastic diffusive solids under concentrated load. The results offer valuable insights for applications in advanced materials science, microscale and nanoscale engineering and dynamic load analysis, where it is crucial to understand the combined effects of nonlocality, thermoelasticity and diffusion.
