New Method of Determination for Pressure and Shear Frictions in the Ring Rolling Process as Analytical Function

Ring rolling is one of the most significant methods for producing rings with highly precise dimensions and superior qualities such as high strength uniformity, all accomplished without wasting any materials. In this article, we have achieved analytical formulas for calculating the pressure and shear friction over the contact arcs between the rollers and ring in the ring rolling process for the ...

Wellbore associated problems due to gas injection into non-horizontal structures

The rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. Also, CO2 sequestration into the depleted reservoirs has attracted a large attention recently. However, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...

بررسی تأثیر محصورشدگی بتن در رفتار غیرخطی دیوارهای برشی بتن‌آرمه بالدار

Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...

Force Reduction Factor R for Shear Dominated Low-Rise Brick Masonry Structures

This paper presents investigation carried out, including experimental and numerical studies, on low-rise shear-dominated brick masonry structures for the calculation of force reduction factor R. Basic experimental tests were conducted on masonry constituent materials for mechancial characterization. In-plane quasi-static cyclic tests were conducted on twelve full scale brick masonry walls, to u...

Palaeostress configuration of Pan-African orogeny: evidence from the Igarra schist belt, SW Nigeria

The stress configuration and tectonic analysis of the Pan – African orogeny is drawn from the Igarra schist belt, southwestern Nigeria. The analysis of conjugate shear fractures of the schist belt indicates that two distinct compressive events (NE – SW and E – W) occurred in this Pan – African mobile zone. The palaeostress systems reveal a clockwise rotation of compressional axis from D1 (NE – ...
