A Modified Indirect Boundary Element Analysis for Fatigue Behavior Assessment of Rock-Like Materials Based on Linear Elastic Fracture Mechanics

R. Alizadeh; M. Fatehi Marji; A. Abdollahipour; M. Pourghasemi Sagand

Volume 12, Issue 4 , October 2021, , Pages 1189-1203

http://dx.doi.org/10.22044/jme.2022.11534.2139

Abstract
  In this work, an effective methodology is introduced for modeling the fatigue crack propagation in linear elastic brittle media. The displacement discontinuity method is used to accomplish the analysis, and the boundaries are discretized with quadratic elements in order to predict the stress intensity ...  Read More

Wellbore Trajectory Optimization of an Iranian Oilfield Based on Mud Pressure and Failure Zone

H. Yousefian; M. Fatehi Marji; H. Soltanian; A. Abdollahipour; Y. Pourmazaheri

Volume 11, Issue 1 , January 2020, , Pages 193-220

http://dx.doi.org/10.22044/jme.2020.8779.1768

Abstract
  Determination of the borehole and fracture initiation positions is the main aim of a borehole stability analysis. A wellbore trajectory optimization with the help of the mud pressure may be unreasonable since the mud pressure can only reflect the degree of difficulty for the initial damage to occur at ...  Read More

Rock Mechanics
Discrete element modeling of explosion-induced fracture extension in jointed rock masses

M. Lak; M. Fatehi Marji; A.R. Yarahamdi Bafghi; A. Abdollahipour

Volume 10, Issue 1 , January 2019, , Pages 125-138

http://dx.doi.org/10.22044/jme.2018.7291.1579

Abstract
  The explosion process of explosives in a borehole applies a very high pressure on its surrounding rock media. This process can initiate and propagate rock fractures, and finally, may result in the rock fragmentation. Rock fragmentation is mainly caused by the propagation of inherent pre-existing fractures ...  Read More
