The statistical size effect in cementitious beams is examined using the assumption that the critical threshold stress to cause a strain-softened fracture process zone to be initiated follows the Weibull distribution. The fictitious crack line model and the K-superposition theory, in combination with
method for determining the fatigue notch-size-effect is presented based upon the development of closure in the wake of a newly formed crack growing from a notch. A comparison with experimental results is in accord with predictions. The effect of crack closure on the formation of non-propagating crac

It has long been known that the fatigue notch factor K F , given by r w0 /r w , where r w0 is smooth specimen fatigue strength (R = À1) and r w is the fatigue strength of a notch-containing specimen, is less than the theoretical stress concentration factor, K T . Empirical rules have been proposed b
