Application of J2 Integral Method in Calculating Complicated Stress Intensity Factors on Three-dimensional Components [PDF]
E3S Web of Conferences, 2021 In this paper, a technique to determine complicated stress intensity factors on three-dimensional components, which based on the conservation law and the elementary mechanics is proposed, it only needs the geometric relationship between multiple singular

Study of overload effects in bainitic steel by synchrotron X-ray diffraction [PDF]
Fracture and Structural Integrity, 2013 This work presents an in-situ characterisation of crack-tip strain fields following an overload by means of synchrotron X-ray diffraction. The study is made on very fine grained bainitic steel, thus allowing a very high resolution so that small changes ...

Modelling probabilistic fatigue crack propagation rates for a mild structural steel [PDF]
Fracture and Structural Integrity, 2015 A class of fatigue crack growth models based on elastic–plastic stress–strain histories at the crack tip region and local strain-life damage models have been proposed in literature.

Fatigue crack shielding in plain bearings under large scale yielding [PDF]
, 2010 Multi-layered bearing systems used in the automotive industry show shielding and antishielding effects that reduce or amplify the crack driving force under large-scale yielding conditions. Using finite element analysis, it is shown that shielding in such

Strain model and experimental study of elastic viscoplastic for crack-tip zone of X80 steel pipe
Journal of Pipeline Science and Engineering, 2022 The mechanical state of the process zone at the crack-tip is one of the main factors that affect crack initiation and growth in the long-term safe operation of oil and gas pipelines. Many tests showed that the stress and strain fields in the fracture-tip

A numerical study of crack shielding and deflection under extensive plasticity [PDF]
, 2009 Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

Strain field measurement around the crack tip in Ni-base superalloy using Digital Image Correlation
Nihon Kikai Gakkai ronbunshu, 2018 Digital Image Correlation (DIC) method was applied to measure the strain fields around the crack tip in a Ni-base single crystal superalloy. DIC systems were assembled to appropriately measure the strain fields at room temperature, 700°C and 900°C ...

Fractures in glaciers—Crack tips and their stress fields by observation and modeling [PDF]
PAMM, 2023 AbstractHigh‐resolution optical camera systems are opening new opportunities to study fractures in ice. Here, we present data obtained from the Modular Aerial Camera System camera system operated onboard of Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) polar aircraft in northeast Greenland in 2022.
