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 ...

Overstraining effects on the crack-opening displacement of microstructurally short cracks

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2005
The influence of different overstraining events on the crack-opening displacement of microstructurally short cracks in polycrystalline nickel was investigated. Both symmetric and asymmetric overstraining experiments were carried out and the influence of increasing overstraining ratio and number of overstraining cycles was analysed.

Crack opening displacement and propagation rate of microstructurally short cracks

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2003
Crack opening displacement (COD) along the edges of microstructurally short fatigue cracks in austenitic stainless steel was investigated in situ in the SEM. The measured plastic part of the COD range between maximum and minimum load was extrapolated to the near crack tip region, assuming plastic blunting and resharpening by cooperative slip as well ...
