Influence of Microstructure Flaw Populations on Fracture Statistics

Influence of Microstructure Flaw Populations on Fracture Statistics 

Other types of flaw distributions can also occur, with such examples being bimodal and multimodal flaw populations [69,70,96], the simultaneous occurrence of volume and surface defects [65, 70], or the occurrence ofnarrow peaked-flaw populations [70, 71]. In order to take into account the influence of several concurrently occurring flaw distributions, their mean numbers per specimen [see Eq. (12) and Ref. [65]] can simply be superposed  

In summary, it must be stated that the strength distribution is a direct function of the size distribution of the flaws which act as fracture origins. The analytical Weibull equation [ Eq. (12)] is a special case of a more general distribution which often - but
