Generalized fracture mechanics of ductile steels
International Journal of Fracture, 1982The generalized fracture mechanics approach is applied to two ductile steels, namely mild steel and 18/8 stainless steel in plane stress. The theory defines a fracture parameter\(\mathcal{T}\), which is a truly plastic analogue of theJ contour integral and, for an edge crack specimen, is given by $$\mathcal{T} = k_1 ( \in _0 )cW_{0_c } $$ wherek1

Fatigue strength and fracture mechanics – A general perspective
Engineering Fracture Mechanics, 2018Abstract Common fracture mechanics based fatigue considerations are usually limited to the residual lifetime determination of so-called long cracks. The extension of this concept to the total lifetime, as in the S-N curve approach, requires an adequate description of short crack propagation which cannot be based on the ΔK concept, and it must ...

SummaryEconomic success in producing oil/gas from low-permeability shale often relies on pre-existing natural fractures (NFs) to be activated or connected by hydraulic-fracturing (HF) stimulation. In practice, the reactivated NF network is often identified with the microseismicity (MS) monitored during the stimulation.

Generalized displacement correlation method for mechanical and thermal fracture of FGM
International Journal of Computational Materials Science and Engineering, 2020The main objective of this work is to present a numerical modeling of mixed-mode fracture in isotropic functionally graded materials (FGMs), under mechanical and thermal loading conditions. In this paper, the displacement-based method, termed the generalized displacement correlation (GDC) method, is investigated for estimating stress intensity factor ...

Nanofracture Mechanics Approach to Dislocation Generation and Fracturing
Applied Mechanics Reviews, 1994As applied to the problem of dislocation nucleation, nanofracture mechanics suggested earlier by the author advances a simpler and more powerful alternative to the Rice-Thomson approach. This alternative is briefly described in the present paper. It is shown that the predictions of nanofracture mechanics differ many times from those of the Rice-Thomson
