Two collinear cracks in a transversely isotropic medium under the hyperbolic heat conduction law

The problem of two collinear cracks in an infinite thermoelastic transversely isotropic medium under non-Fourier heat conduction law is studied. The considered cracks are thermally insulated, which do not admit any disturbances of thermal flow across the cracks. The mode II thermal stress intensity factor and crack opening displacement are derived for a stress free boundary condition and plotted to show the effect of crack length. Moreover, the work shows the thermal stress intensity factor's behaviour in case of a Fourier heat conduction (parabolic) law and for a single crack.
