要約

A definite solution problem of a coupled thermal-mechanical model is considered for in-plane double-layer coatings, subjected to a heat pulse. The general solution of the governing coupled equations is obtained using the dual-phase lag model of the non-Fourier heat conduction law. The temperature increment T and volumetric strain θ are derived, which are related to the logarithmic heat rate ε. A thermal-mechanical failure analysis of the coating system is made and the possible failure mode is also investigated. The results show that the wave front propagates along the interface because of the reflection and superposition at the convex part of the interface. Transient stress intensity factors of mode I are obtained in the double-layer system with cracks close to the interface. Moreover, the influences of different relaxation times and of the radius of the interface curvature are discussed.
