An edge crack surrounded by a slender, triangularly-shaped elastic inclusion is used to represent an experimentally-observed crack layer generated by constant amplitude fatigue conditions. Approximate but explicit formula is derived for the stress-intensity factor. As a byproduct, the exact stress-intensity factor for the title problem is explicitly obtained.
