Micromechanical analysis of sand production

Micromechanical Analysis of Random Composites

Micromechanical Analysis of Random Composites by Michal Šejnoha and Jan Zeman Effective elastic properties are found for a fibrous graphite-epoxy composite system with fibers randomly distributed within a transverse plane section of the composite aggregate. Two different approaches are examined. The first approach assumes a well defined geometry of the fiber arrangement and specific boundary co...

Development of Contactless Sand Production Test Instrument

Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Micromechanical Analysis of Thermal Expansion Coefficients

Thermal expansion coefficients play an important role in the design and analysis of composite structures. A detailed analysis of thermo-mechanical distortion can be performed on microscopic level of a structure. However, for a design and analysis of large structures, the knowledge of effective material properties is essential. Thus, either a theoretical prediction or a numerical estimation of t...

Hazards Analysis of Displacement of Sand Dunes in Sistan Plain

In Sistan plain, conditions for wind erosion and, consequently, sand spreads are provided. Due to the settlements in the wind erosion centers of this area, the necessity of determining the origin of sands, the analysis of the hazards caused by the displacement of sand dunes and factors creating these hazards are the goals of this study. It is a descriptive-analytical study based on both field a...
