Direct evaluation of T " integral from experimentally measured near tip displacement ®eld, for a plate with stably propagating crack
In this paper, a method for quantitatively evaluating the T " integral, directly from the measured near-tip displacement ®eld in laboratory specimens made of metallic materials, is presented for the ®rst time. Following Okada and Atluri (Okada, H., Atluri, S.N., 1999. Further studies on the characteristics of the T " integral: plane stress stable crack propagation in ductile materials. Computat...
متن کاملDisplacement Discontinuity Analysis of the Effects of Various Hydraulic Fracturing Parameters on the Crack Opening Displacement (COD)
The combination of horizontal drilling along with hydraulic fracturing has significantly improved the production of hydrocarbon reservoirs and made it possible to extract the relatively impermeable and uneconomical reservoirs. The production rate of oil and gas wells increases proportional to hydraulic fracture aperture or crack opening displacement (COD). This is an important parameter i...
متن کاملPlane Strain Deformations of Locking Materials near a Crack Tip
Plane-strain deformations of an isotropic and homogeneous Hookean body containing a crack are studied and it is required that the dilatation everywhere in the body be. greater than or equal to a constant. Following Prager, the region where the dilatation always equals the constant is identified as the locking region. For the case when the deformations of the body are symmetrical about the plane...
متن کاملEstimation of Stress Intensity Factors from Near Crack Tip Field
All current experimental methods for determination of stress intensity factors are based on the assumption that the state of stress near the crack tip is plane stress. Therefore, these methods rely on strain and displacement measurements made outside the near crack tip region affected by the three-dimensional effects or by process zone. In this paper, we develop and validate an experimental pro...
