Crack growth rate of an inclined surface crack

Engineering Fracture Mechanics, 1992
Investigation of surface crack growth in 16MnR steel specimens with crack inclination angle β = 0°, 30° and 45° and under the condition of biaxial loading ratio Px:Py = 0, 0.5 and 1 is reported in this paper. A formula of the stress intensity factor for surface cracked cruciform specimens loaded biaxially is calibrated using the finite element method ...

Crack opening displacement and the rate of fatigue crack growth

International Journal of Fracture Mechanics, 1972
Using a direct proportionality between the rate of fatigue crack growth and crack opening displacement above a threshold, it is shown that fatigue crack growth data for a wide variety of different materials can be accurately described in terms of the mechanical properties and two material constants; the constant of proportionality A and the threshold ...

The Rate of Growth of Fatigue Cracks

Journal of Applied Mechanics, 1936
Abstract The author discusses the resistance of metal to the propagation of cracks, and points out that in the accepted method of fatigue testing the results are not conclusive because there is no distinction between (1) the load and the number of repeated stresses required to start cracks and (2) the load and the number of reversals ...

Crack growth rate in bent rods

Strength of Materials, 1991
It was shown experimentally on rectangular epoxy rods ruptured by bending that a stress raiser on the surface of the rod, and also an addition of plasticizer to the material, reduce the crack growth rate. The effect of reducing the crack growth rate makes it possible to retain a rectilinear path of crack propagation when there are long arms of load ...

Crack growth rate and cracking velocity in fatigue for a class of ceramics

Theoretical and Applied Fracture Mechanics, 1999
Abstract Fatigue crack growth rate data and cracking velocity data are studied for a class of ceramics including SiC, TiB2, Si3N4, ZrO2 and Al2O3. Both sine and square wave cyclic loading are combined such that the data could be converted to cracking velocity for a given frequency of cyclic load.

Fatigue crack path manipulation for crack growth rate measurement

Engineering Fracture Mechanics, 2016
Abstract It is accepted that fatigue crack paths in metals that display confined slip, such as high strength aluminium alloys, are responsive to loading direction and local microstructural orientation. It is less well recognised that crack paths in these alloys are also responsive to the loading history since certain loading sequences can produce ...

Fatigue Crack Growth Rate Data Assessment

Volume 4: Materials and Fabrication, 2021
Abstract A comprehensive fatigue test database was developed in PRCI SIA-1-1 and IM-3-2 projects, where there are 185 sets of fatigue crack growth rate parameters (i.e., C and m fitting coefficients in the Paris law) calculated from compact tension (CT) fatigue test data.
