Constant-probability crack growth curves
Engineering Fracture Mechanics, 1988Abstract This paper details a stochastic, time-inhomogeneous model that serves as a theoretical basis for the prediction of crack growth and its variability under constant-amplitude loading. Crack evolution is described as a set of constant probability curves, each of whose points possess equal probability of advancing from one position to another ...

Crack Growth Resistance Curves (R-Curves)- Literature Review
1973The development of the concept of crack-growth resistance as a means of characterizing fracture toughness is reviewed. While the first model was proposed in 1954, major developments, experimental determinations, and applications of R-curves date from 1960.

An R-Curve for a Surface Crack in Titanium
1981R-curves for surface cracks in Ti-6A1-4V titanium alloy were generated for the purpose of studying the resistance of the alloy to their subcritical growth under a monotonically increasing load typical of a proof test. Another purpose was to evaluate Ehret's compliance calibration for measuring the instantaneous size of a surface crack using the ...

On fracture analysis of cracked curved beams
Journal of Mechanical Science and Technology, 2018This paper focuses on evaluating stress intensity factors (SIFs), for a curved beam of circular cross section with an external ring crack, applying an approach on the basis of estimating the strain energy release rate. The out of plane vibration of the beam is investigated.

Further Studies on Dynamic Crack Curving
1981Abstract : The elasto-dynamic stress field surrounding rapidly propagating cracks in thin polycarbonate, double edged crack tension specimens were analyzed by dynamic photoelasticity using a 16-spark gap Cranz-Schardin camera system. Crack curving was observed in two slanted double edged crack specimens and in two offset parallel double edged crack ...
