Analytical model of thermal striping for a micro-cracked solid

Using the formal asymptotic approximation of the Mode I stress intensity factor for an edge crack in a thermoelastic half plane containing several small voids obtained in [Nieves, M.J., Movchan, A.B., and Jones, I.S., 2011. Asymptotic study of a thermoelastic problem in a semi-infinite body containing a surface-breaking crack and small perforations. QJMAM 64 (3), 349–369] we investigate the effect of micro-cracks on this stress intensity factor. In numerical examples, we show how the behaviour of the stress intensity factor as a function of crack depth is affected by micro-cracks of different orientations occurring in the half space.
