Evolution mechanism of optical fiber strain induced by multi-fracture growth during fracturing in horizontal wells

Petroleum Exploration and Development, 2022
A forward model for optical fiber strain was established based on a planar 3D multi-fracture model. Then the forward method calculating distributed fiber strain induced by multi-fracture growth was proposed.

Sheared edge formability of multi-phase steels under in- and out-of-plane deformation [PDF]

MATEC Web of Conferences
Multi-phase advanced high strength steels can exhibit significant sheared edge sensitivity due to their microstructures and alloying elements. Processing defects such as centerline segregation of martensite or Ti-based inclusions can affect edge ...

Hot tensile deformation behaviors and a fracture damage model of the Mg-Gd-Y-Zn-Zr alloy

Journal of Materials Research and Technology, 2022
In this study, the hot deformation of Mg-9Gd-4Y-2Zn-0.5Zr alloy was studied by the hot tensile test conducted at various temperatures (350°C–500 °C) and strain rates (0.0001–0.1s−1).

Application of Far Cortical Locking Technology in Periprosthetic Femoral Fracture Fixation: A Biomechanical Study [PDF]

, 2016
© 2016 Elsevier Inc. Background Lack of fracture movement could be a potential cause of periprosthetic femoral fracture (PFF) fixation failures. This study aimed to test whether the use of distal far cortical locking screws reduces the overall stiffness ...

Hot tensile deformation behavior and a fracture damage model of the wrought Mg–Gd−Y–Zn–Zr alloy

Journal of Materials Research and Technology, 2023
The hot deformation behavior of the wrought Mg–Gd−Y–Zn–Zr alloy was studied by uniaxial tensile tests conducted at various temperatures (350–500 °C) and strain rates (0.1–0.0001s−1).

On the fracture of human dentin: Is it stress‐ or strain‐controlled? [PDF]

Journal of Biomedical Materials Research Part A, 2003
AbstractDespite substantial clinical interest in the fracture resistance of human dentin, there is little mechanistic information in archival literature that can be usefully used to model such fracture. In fact, although the fracture event in dentin, akin to other mineralized tissues like bone, is widely believed to be locally strain‐controlled, there ...

Spall And Dynamic Yielding Of Aluminum And Aluminum Alloys At Strain Rates Of 3X10(6) S(-1) [PDF]

, 2009
We have explored the role that grain size, impurity particles and alloying in aluminum play in dynamic yielding and spall fracture at tensile strain rates of similar to 3x10(6) We achieved these strain rates shocking the aluminum specimens via laser ...

Effect of strain rate and stress triaxiality on fracture strain of 304 stainless steels for canister impact simulation

Nuclear Engineering and Technology, 2022
In this paper, smooth and notched bar tensile tests of austenitic stainless steel 304 are performed, covering four different multi-axial stress states and six different strain rate conditions, to investigate the effect of the stress triaxiality and ...
