The distinct characteristic of subcritical propagation requires at least two control parameters to completely express expansion of cracks in the concrete. The basic definition of crack tip opening displacement (CTOD) is corrected based on the monitored variable of crack mouth opening displacement (CMOD).

International Journal of Fracture, 2002
This paper examines the effects of crack front curvature on the fracture toughness (crack-tip opening displacement) of A707 steel. Fracture mechanics specimens, in which the radii of curvature of the crack fronts are controlled in an effort to simulate potential variations in crack front profiles in fracture experiments, were produced by machining and ...

Relation Between J-Integral and Crack Tip Opening Displacement
1981This paper describes the analysis by the finite element method, which shows the correlation between the J-integral (J) and crack tip opening displacement (CTOD). The result is that the non-dimensional J-integral ~ non-dimensional CTOD relation seems to be expressed by a single curve for various metals.

Relationships Between Various Definitions of the Crack Tip Opening Displacement
1986A close examination of the CTOD problem reveals that the crack tip opening displacement is very much a matter of definition. Various definitions are in use either for analytical treatment or for experimental determination. A comparison of these shows that by the widely used experimental methods a quantity is determined which is at variance with the ...

A Crack-Tip Opening Displacement Method for the Analysis of Ductile Materials
1988Although crack-tip opening displacement (CTOD) analysis procedures are well established for the prediction of tolerable crack sizes in ferritic steels, no specific procedures exist which incorporate a resistance (R) curve to facilitate estimation of the ductile instability conditions for a fully ductile material.

An Analytical Elastic-Plastic Solution of Crack Tip Opening Displacement
2003A thin plate with a straight crack is considered. It is assumed that the plate material is ductile and that plastic zones around crack tips will occur under loading. This means that in these zones the material yields and the phenomenon of crack opening is started.
