Notched Flexcural Strength of Soda-lime Glass

LU Bao-Tong; WEN Chao(Northwestern Polytechnical University Xi'an 710072 China)  
The flexural strength of soda-lime glass σnb is inversely proportional to the theoretical stress concentration factor of specimens Kt but the fracture stress at notch root σf(=ktσnb) is independent of Kt. When the flexural strength follows Weibull distribution, the modulus m is a material constant hilt the scale factor ac changes inversely with kt. When the fie-cural strength follows Gauss distribution, both the mean value and the standard diviation of the flexural strength are inversely proportional to the Kt, but the coefficient of variation of the fie-cural strength is a material constant.
