摘要：
The mechanism of initiation and propagation of wing crack emanating from the tips of closed flaw under compressive stresses is discussed. The approximate expression of stress intensity factor for relatively long wing crack was derived and was found to agree well with the detailed numerical result. A wing crack extends stably where mode-I stress intensity factor decreases with the extension of crack. Wing crack propagation in an infinite domain as well as wing crack propagation in a semi-finite and finite regions were treated. Deflection of the surrounding boundaries was found to accelerate the growth of wing crack.
