TL;DR: In this article, the authors used a double cantilever beam (DCB) to determine the mode I interlaminar fracture toughness, or critical energy release rate, of composites.

TL;DR: The statistical scatter in fracture toughness of high strength materials obtained from the existing empirical correlations is compared with the scatter observed in the nominally identical fracture toughness tests as discussed by the authors, and it is found that the correlation of fracture toughness with Charpy V-notch impact energy will be more useful for all practical purposes.

TL;DR: In this paper, a fracture analysis has been carried out on M300 grade maraging steel cylindrical vessels with the inner semi-elliptical surface crack, and three parameter fracture criterion which relates the stress and the elastic stress intensity factor at failure, is followed for the development of a failure assessment diagram.

TL;DR: In this paper, an empirical relationship between the failure stress and the elastic stress intensity factor at failure was established by means of three fracture toughness parameters (K F, m, and p ) of 34Cr Mo4 grade steel material.

TL;DR: In this article, a relation between the elastic stress intensity factor and the elastic nominal stress (net section) at failure is established using the crack growth resistance curve (R- curve ), generated from a compact tension specimen.
