Geology of the northwestern portion of the Ferriere-Mollieres Shear Zone, Argentera Massif, Italy

open access: yes, 2016
The Ferriere-Mollieres Shear Zone (FMSZ) is a regional shear zone cross-cutting the Argentera External Crystalline Massif (Western Alps). It shows a NW-SE striking dextral shear zone separating two Variscan migmatitic complexes: the Tinèe to the SW and ...

Application of Moving Kriging Shape Functions on Plate Problems

open access: yesNUST Journal of Engineering Sciences, 2008
The Moving Kriging (MK) interpolation was recently proposed as a superior substitution of the Moving Least Square (MLS) approximation in the construction of shape functions for the Element-Free Galerkin Method (EFGM).

Numerical investigation of casing shear deformation due to fracture/fault slip during hydraulic fracturing

open access: yesEnergy Science & Engineering, 2020
The frequent occurrence of casing failure has significantly affected the development of shale gas in the Sichuan Basin. Based on engineering and geology analyses, natural fracture/fault slip leads to casing shear deformation during hydraulic fracturing ...
