Crack opening displacements of Vickers indentation cracks

Engineering Fracture Mechanics, 2005
Vickers indentation cracks are an appropriate tool to determine the crack-tip toughness KI0 and, possibly, the bridging relation of ceramics with an R-curve behaviour from the total crack opening displacements. Two contributions to the total crack opening displacement field are addressed. First, the residual stresses occurring in the uncracked body are

Studies on crack opening displacements

International Journal of Pressure Vessels and Piping, 1987
Abstract Experiments on thin sheets of 6063-T6 Al-alloy having a central notch were performed in order to examine if the displacements measured near and behind the crack tip bear some relationship to the theoretical crack opening displacements (COD)/crack tip opening displacements (CTOD) found by equations that have been modified to account for the ...

A crack opening displacement approach to crack patching

Engineering Fracture Mechanics, 1980
Abstract The results of a numerical investigation into crack patching indicate that a modified form of the crack opening displacement approach may be useful in estimating the effect that fibre composite patches have on cracks in thin sheets.

A new method of crack-tip opening displacement determined based on maximum crack opening displacement

Engineering Fracture Mechanics, 2011
Abstract In this paper a new method is presented to determine the crack-tip opening displacement (CTOD) for the center cracked plate with uniaxial uniform tension load. The maximum crack opening displacement (MCOD) is adopted to estimate CTOD. Based on the series of calculation results by elastic–plastic finite element simulation, an explicit ...

Crack-opening-displacement measurements of a dynamically loaded crack

Engineering Fracture Mechanics, 1971
Abstract The crack-opening-displacement of a dynamically loaded crack in a plate of Araldit B has been measured using a simple optical interference technique and high speed photography. The goal of these investigations was to experimentally determine the dynamic stress intensity factor as a function of time up to about 100 μ sec after load ...

Critical Crack Opening Displacement

2003
A three-point bend specimen with S = 25 cm, W = 6 cm, a = 3 cm, and B = 3 cm is used to determine the critical crack opening displacement δc of a steel plate according to the British Standard BS 5762. The load versus crack mouth displacement (P — V) record of the test is shown in Figure 1.

Crack opening displacement in pressurized spheres with surface cracks

International Journal of Fracture, 1985
The crack opening displacement at the centre of a surface crack in a pressurized sphere has been calculated using a strip yielding model. The shallow shell solution for the stress intensity factor derived by Folias has been extended to derive the COD, and the resulting equations have been solved numerically by a procedure due to Erdogan.

The effect of shallow cracks on crack tip opening displacement

Engineering Fracture Mechanics, 1986
Abstract 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.

An approximative crack opening displacement field for embedded cracks

Engineering Fracture Mechanics, 1989
Abstract For the application of Cruse and Besuner's method to calculate approximative energy release rates or “averaged weighted stress intensity factors” the crack opening displacement field of the considered crack has to be known for a reference loading case. In this paper an embedded elliptical crack is investigated.
