Abstract

This study adopts a 3D model of a double cantilever beam with interlayer defects under pulsed laser. The type II stress intensity factor at the 3D crack tip of the interlayer and its variation with time are obtained via displacement extrapolation under the classical thermoelasticity and generalized thermoelasticity, respectively, and using the non-Fourier heat conduction equation. The effects of thickness ratio, crack tip position, and heat source at different positions are discussed.
