✦ Synopsis

The transient thermoelastic response of a thin composite plate composed of a dominant matrix and an insert is investigated. The plate is heated by exposing the matrix to a heating source in the form of a step function. The hyperbolic heat conduction model is used to determine the thermal behavior of the plate, which is assumed to be lumped in the transverse direction. The dominant temperature of the matrix is used to evaluate the thermal stresses. The effects of the heating source intensity and time duration, the insert volume fraction and the convection coefficients on the temperatures and thermal stresses are investigated and presented. The thermal stresses generated within the plate are found to be compressive, follow the behavior of the temperature, and largely affected by the heating source intensity and duration.
