Membrane stress is mi, stress concentration coefficient of mismatch amount is Kh, stress concentration coefficient of angularity Kw，the material constant C in Formula Paris, fluctuating stress amplitude is Δσ, originate crack depth is a0 and critical crack opening displacement(COD) is δc, and they are all regarded as mutually independent random variables in science of statistics.
The calculating results of related coefficient of two random number are as followed: The dual variable related coefficient of originate crack depth a0 is -0.60;Membrane stress is -1; Fluctuating stress amplitude Δσ is -1; Material constant C is -0.98; Stress concentration coefficient of mismatch amount Kh is -0.04; Stress concentration coefficient of angularity Kw is -0.25; Critical COD δc is -0.04; The dual variable related coefficient in discriminate (9) is less than 1.Therefore, the variance calculated by above-mentioned procedure will be less than that by direct sampling method.
