✦ Synopsis
In
this paper a correction similar to the Seewald-Karman correction for beams of rectangular cross-section subjected to flexure, is estimated and used in fracture statistics of round brittle beams under flexure. When the specific risk of fracture function is the Weibull function the volume and the surface cumulative probabilities of fracture are obtained. When the specific risk of fracture function is unknown, then integral equations are solved in order to obtain this function. The volume and surface .functions are obtained separately when the material is exhibiting volume and surface brittleness at the same time. The Fisher information matrix is used to get the dispersion of Weibull's parameters.
