The present study is an investigation of the effects of non-locality and dual-phase-lags in a thermoelastic half-space subjected to thermomechanical loading. A homogeneous isotropic nonlocal thermoelastic diffusive half space with dual phase lag is explored.The governing equations are solved with the help of harmonic vibration analysis in collaboration with Fourier transform techniques. The distributed sources are considered to demonstrate practical relevance. Further, they are categorized as uniformly distributed sources and linearly distributed sources for mechanical, thermal, and chemical potential excitations. Numerical simulations are performed using software MATLAB (R2016a) to evaluate displacements, stresses, temperature variations, and chemical potential, where the results are presented graphically for proper clarity. Moreover, the particular limiting cases are also examined to validate the model and highlight key behaviors. The study is applicable in order to predict thermal and mechanical responses in electronics, MEMS/NEMS devices, aerospace components, and energy systems subjected to timeharmonic loads.
