1. On Propagation Mechanism of Cracks Emanating from Two Neighboring Holes in Cubic Concrete Specimens under Various Lateral Confinements

M. Davood Yavari; H. Haeri; V. Sarfarazi; M. Fatehi Marji; H. A. Lazemi

Articles in Press, Accepted Manuscript, Available Online from 01 July 2021

http://dx.doi.org/10.22044/jme.2021.10834.2054

Abstract
  The propagation mechanism of cracks emanating from two holes within the concrete specimens is studied by considering the effects of different lateral compressive stresses. The experimental part of this research work is carried out on some specially prepared pre-cracked specimens with two neighbouring ...  Read More

2. Compressive Failure Analyses of Rock-Like Materials by Experimental and Numerical Methods

M. Davood Yavari; H. Haeri; V. Sarfarazi; M. Fatehi Marji; H. A. Lazemi

Volume 12, Issue 3 , Summer 2021, , Pages 769-783

http://dx.doi.org/10.22044/jme.2021.10819.2052

Abstract
  Investigating the crack propagation mechanism is of paramount importance in analyzing the failure process of most materials. This process may be exposed during each kind of loading on the materials. In this work, the cracking mechanism in rock-like materials is studied using the numerical methods and ...  Read More

3. On Direct Tensile Strength Measuring of Anisotropic Rocks

V. Sarfarazi; H. Haeri; M. Fatehi Marji

Volume 12, Issue 2 , Spring 2021, , Pages 491-499

http://dx.doi.org/10.22044/jme.2021.10601.2013

Abstract
  The tensile strength of the anisotropic rock-like material specimens is meastred directly in the laboratory using a new device converting the compressive loading to that of the tensile before the rock breakage. The specially prepared concrete slabs of dimensions 19 cm * 15 cm * 15 cm with a central hole ...  Read More

4. Hydraulic fracture propagation: analytical solutions versus Lattice simulations

E. Bakhshi; V. Rasouli; A. Ghorbani; M. Fatehi Marji

Volume 10, Issue 2 , Spring 2019, , Pages 451-464

http://dx.doi.org/10.22044/jme.2019.7726.1638

Abstract
  In this work, we used a grain-based numerical model based on the concept of lattice. The modelling was done to simulate the lab experiments carried out on the mortar samples. Also the analytical solutions corresponding to the viscosity-dominated regime were used to estimate the fracture length and width, ...  Read More

5. Behavior of a hydraulic fracture in permeable formations

A. Abdollahipour; M. Fatehi Marji; H. Soltanian; E. A. Kazemzadeh

Volume 9, Issue 4 , Autumn 2018, , Pages 893-904

http://dx.doi.org/10.22044/jme.2018.6129.1428

Abstract
  The permeability and coupled behavior of pore pressure and deformations play an important role in hydraulic fracturing (HF) modeling. In this work, a poroelastic displacement discontinuity method is used to study the permeability effect on the HF development in various formation permeabilities. The numerical ...  Read More

6. A boundary element/finite difference analysis of subsidence phenomenon due to underground structures

S. E. Mirsalari; M. Fatehi Marji; J. Gholamnejad; M. Najafi

Volume 8, Issue 2 , Spring 2017, , Pages 237-253

http://dx.doi.org/10.22044/jme.2016.759

Abstract
  Analysis of the stresses, displacements, and horizontal strains of the ground subsidence due to underground excavation in rocks can be accomplished by means of a hybridized higher order indirect boundary element/finite difference (BE/FD) formulation. A semi-infinite displacement discontinuity field is ...  Read More

7. Rock mass structural data analysis using image processing techniques (Case study: Choghart iron ore mine northern slopes)

M. Mohebbi; A.R. Yarahmadi Bafghi; M. Fatehi Marji; J. Gholamnejad

Volume 8, Issue 1 , Winter 2017, , Pages 61-74

http://dx.doi.org/10.22044/jme.2016.629

Abstract
  Presence of joints and fractures in rocks strongly influences the behavior of the rock mass by dividing the media into smaller units. These structures intensify the potential instability besides the development of sliding and rotational movements. The assumption of discontinuum media changes the whole ...  Read More

8. Numerical investigation of effect of crack geometrical parameters on hydraulic fracturing process of hydrocarbon reservoirs

A. Abdollahipour; M. Fatehi Marji; A. R. Yarahmadi Bafghi; J. Gholamnejad

Volume 7, Issue 2 , Summer 2016, , Pages 205-214

http://dx.doi.org/10.22044/jme.2016.532

Abstract
  Hydraulic fracturing (HF), as a stimulation technique in petroleum engineering, has made possible the oil production from reservoirs with very low permeability. The combination of horizontal drilling and multiple HF with various perforation angles has been widely used to stimulate oil reservoirs for ...  Read More

9. A boundary element analysis of crack-propagation mechanism of micro-cracks in rock-like specimens under a uniform normal tension

http://dx.doi.org/10.22044/jme.2015.362

Abstract
  In this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. The oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. The present work focuses on the interactions ...  Read More
