Experimental and Numerical Investigation of Rock Dynamic Fracture
Rapid development of engineering activities expands through a variety of rock engineering processes such as drilling, blasting, mining and mineral processing. These activities require rock dynamic fracture mechanics method to characterize the rock behavior. Dynamic fracture toughness is an important parameter for the analysis of engineering structures under dynamic loading. Several experimental...
متن کاملExperimental Investigation and Numerical Prediction of Fatigue Life in Force Fitted Fastener Holes
In this paper, the effect of interference fit on fatigue life of holed plate of mechanical joints was investigated experimentally. Fatigue tests were carried out on the holed specimens of Al-alloy 7075-T6 alloy. The interference fit process consists of force fitting a fastener into the hole with a negative clearance (diameter of the fastener is larger than of the hole) that produces beneficial ...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Investigation of a hydraulic impact: a technology in rock breaking
Finite element method and dimensional analysis have been applied in the present paper to study a hydraulic impact, which is used in a non-explosive rock breaking technology in mining industry. The impact process of a high speed piston on liquidwater, previously introduced in a borehole drilled in rock, is numerically simulated. The research is focused on the influence of all the parameters invo...
متن کاملNumerical Investigation of Effect of Rock Bolt Angle on Shear Behavior of Rock Bridges
In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...
