Physico-chemical and micro-structural behavior of cemented mine backfill: Effect of pH in dam tailings
(Elsevier, 2022)
The tailings created during ore processing have been a serious problem for mining companies and environment since it is a challenging task to effectively manage these highly voluminous/dangerous tailings. Therefore, several ...
Simulate of edge and an internal crack problem and estimation of stress intensity factor through finite element method
(Techno-Press, 2022)
In this study, the elastic plane problem of a layered composite containing an internal or edge crack perpendicular to its boundaries in its lower layer is examined using numerical analysis. The layered composite consists ...
Solving the contact problem of functionally graded layers resting on a HP and pressed with a uniformly distributed load by analytical and numerical methods
(Techno-Press, 2022)
The aim of this study is to examine the frictionless double receding contact problem for two functionally graded (FG) layers pressed with a uniformly distributed load and resting on a homogeneous half plane (HP) using ...
Suture button fixation method used in the treatment of syndesmosis injury: A biomechanical analysis of the effect of the placement of the button on the distal tibiofibular joint in the mid-stance phase with finite elements method
(Elsevier, 2022)
Purpose: The purpose of this study is to research the effect of suture button (SB) fixation, a method used at the treatment of ankle syndesmosis injury, which was applied in various angles, pretension force, and levels, ...
Evaluation of the contact problem of functionally graded layer resting on rigid foundation pressed via rigid punch by analytical and numerical (FEM and MLP) methods
(Springer, 2022)
In this paper, frictionless contact problem for a functionally graded (FG) layer is considered. The FG layer is subjected to load with a rigid punch and the FG layer is bonded on a rigid foundation. Analysis of this contact ...
Influence of 3D-printed polymer structures on dynamic splitting and crack propagation behavior of cementitious tailings backfill
(Elsevier, 2022)
Originally developed for polymer materials, 3D printing is an encouraging technique to create versatile geometric shapes and high-precision construction elements from various materials. 3D-printed polymer structures are ...
Effect of height to diameter ratio on dynamic characteristics of cemented tailings backfills with fiber reinforcement through impact loading
(Elsevier, 2022)
The safety and durability of underground backfilled stopes of metalliferous mines are so crucial owing to several dynamic events such as rock bursting, loads triggered by blasting, and loading conditions under stress. ...
Strength, acoustic, and fractal behavior of fiber reinforced cemented tailings backfill subjected to triaxial compression loads
(Elsevier, 2022)
Overall, solid materials like CTB (i.e., cemented tailings backfill) give out low-level seismic signals as they are under stress in underground mining applications involving ground control, rock burst, and coal bump ...
Compressive fatigue behavior and failure evolution of additive fiber-reinforced cemented tailings composites
(Springer, 2022)
The ordinary cemented tailings backfill (CTB) is a cement-based composite prepared from tailings, cementitious materials, and water. In this study, a series of laboratory tests, including uniaxial compression, digital image ...
Employing U-shaped 3D printed polymer to improve flexural properties of cementitious tailings backfills
(Elsevier, 2022)
The roof stability of artificial structures constructed by cementitious tailings backfill (CTB) is one of the major aspects in the durability of underhand cut and fill mining method. This is because CTB's failure can ...
