Analytical solution of a rotating semiconductor elastic medium due to a refined heat conduction equation with hydrostatic initial stress

Autor: Kh. Lotfy, A. El-Bary, E.A. Ismail, Haitham M. Atef

Publikováno v: Alexandria Engineering Journal, Vol 59, Iss 6, Pp 4947-4958 (2020)

The semiconductor elastic medium in the context of the photothermal theory under the influence of rotation field is studied. A novel model of the governing equations is investigated due to the refined multi-phase-lags with the thermal relaxation time
