The Effects of Shear on Mode II Delamination: A Critical Review [PDF]
Fracture and Structural Integrity, 2018 The paper focuses on the effects of shear deformation and shear forces on the mode II contribution to the energy release rate in delaminated beams. A critical review of the relevant literature is presented, starting from the end-notched flexure test as ...

Effect of Rock Fracture Filling on Mode I and II Fracture Toughness [PDF]
Journal of Aalytical and Numerical Methods in Mining Engineering, 2019 This paper focuses on some fracture toughness tests performed on the pre-cracked Brazilian specimens of rock-like materials. Also the effect of rock fracture filling on the fracture toughness was considered experimentally. Fracture toughness is a key parameter for studying the crack propagation and fragmentation processes in rock structures.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Impact of Mode I and Mode II Fractures on Fracture-Gas Permeability in Shale: An Experimental Study
IOP Conference Series: Earth and Environmental Science, 2020 AbstractThe natural-fracture network and a large part of hydraulic fractures are poorly supported, and the conductivity of the natural-fracture network is highly sensitive to stress and strain during the production stage. In this work, we aimed to understand the impact of mode I (tensile) and mode II (shear) fractures on fracture-gas permeability as a ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

AbstractAs the inherent nature of rocks, natural cracks play a remarkable part in controlling the mechanics and permeability responses in rock masses. Due to the intense stress concentration at their neighborhoods, these cracks are extensively recognized as the initial locations for the initiation, extension, and convergence of cracking.
