V. Tamuzs et al., THERMAL FRACTURE OF MACROCRACK WITH CLOSURE AS INFLUENCED BY MICROCRACKS, Theoretical and applied fracture mechanics, 21(3), 1994, pp. 207-218
The fracture stability of macrocracks under uniform heat flux is analy
zed to include the effect of a system of microcracks. The interaction
of cracks leads to full or partial closure of crack surfaces. The boun
dary problem is stated and a solution is obtained. The domains where m
icrocracks are closed and/or affect partial closing of the macrocrack
are found. Evaluated is the macrocrack tip stress intensity factor acc
ounting for closure.
