The effect of shallow cracks on crack tip opening displacement
Engineering Fracture Mechanics, 1986Abstract Further results given in the present paper confirm that shallow cracks have larger crack tip opening displacements at initiation than deep cracks. This difference in behaviour is shown to be principally caused by the different hydrostatic stresses existing at the tips of shallow and deep cracks.

Critical crack tip opening displacement for polymer composites
Engineering Fracture Mechanics, 1989Abstract Applicability of critical stress intensity factor ( K IC ) and/or critical crack up opening displacement (CTODc for epoxy and polyester polymer composites (PC) in mode I Fracture are investigated. Both unreinforced and glass fiber reinforced polymer composite systems are studied using single edge notched beams in three-point and ...

The stereophotogrammetric determination of the critical crack tip opening displacement
Engineering Fracture Mechanics, 1985Abstract The methods to determine the critical crack tip opening displacement (CODi) are discussed. Stretched zone regions are analyzed using the method of stereophotogrammetry with the scanning electron microscope. The CODi is determined on eight sections near the centre of the specimen.

Crack Tip Opening Displacement of X100 SAWL Pipe
Advanced Materials Research, 2011The fracture toughness of different zones of X100 SAWL pipe was studied by three-point bend test method under different temperature. At the same temperature, the crack propagation resistance and tear modulus of X100 SAWL pipe distributed as: base metal>HAZ>weld bead, and the distribution of the CTOD value of X100 SAWL pipe is :base metal >weld

On the cyclic crack‐tip opening displacement
Fatigue & Fracture of Engineering Materials & Structures, 2009ABSTRACTThis note discusses the cyclic crack tip opening displacement (CTOD)cyc. As is discussed, the correct expression for the (CTOD)cycis based upon the effective range of the stress intensity factor.
