Fracture statistics of torsion and dispersion relations in round bars

G. Díaz

This paper has adopted a theoretical viewpoint for studying Fracture Statistics in round bars subjected to torsion, and for determining the cumulative probabilities of fracture using Weibull's specific-risk function for materials that exhibit volume and surface brittleness. The use of the defined-functions method has allowed to get the specific-risk-of-fracture function and, in addition, to carry out a separation between volume part and surface part concerning materials presenting both brittlenesses at the same time. Dispersion of the parameters are determined resorting to Fisher's information matrix.
