Thermoelasticity behavior of a crack in solids is studied based on dual phase lag heat conduction model.
- ss="label">•
Insulated crack and heated crack are studied and inertia effect is considered.

Non-Fourier effect is strong for large temperature gradient lag to heat flux lag ratio.

Inertia effect can be ignored if the thermal wave speed is one order smaller than shear wave velocity.
