In this paper, the axial stress and deformation of high temperature high pressure super-deep deviated gas wells are studied. A new model presents multiple nonlinear equation systems, which comprehensively consider the axial load of the tubular string, internal and external fluid pressure, normal pressure between the tube and well wall, friction and the viscous friction of fluid flowing under va...

AbstractHydroforming process is a deep stretching process only with the difference that a fluid is used instead of the mandrel. This paper investigates the hydroforming process of non-cylindrical and non-spherical geometries using finite element analysis software to calculate the influences of effective process parameters such as the coefficient of friction between the surfaces and the pressure...

Understanding sheet metal forming presses are important to reduce manufacturing costs. Thus, the best method of finding optimum values processing is by studying effect parameters on behavior formability, friction, and die radius. In this work, deep drawing process a low-carbon steel cup was studied significance two investigated which friction coefficient radius die. The finite element program, ...

BACKGROUND Deep transverse friction massage (DTFM) is one of several physiotherapy interventions suggested for the management of pain due to iliotibial band friction syndrome (ITBFS). OBJECTIVES To assess the effectiveness of DTFM for treating ITBFS observed in runners. SEARCH STRATEGY We searched the Medline, Embase, Healthstar, Sports Discus, CINAHL, the Cochrane Controlled Trials Registe...

In this paper, the drawing process of multi-layer sheet metal through wedge shaped die has been analyzed using stream function and upper bound method. Typically a sandwich sheet contains three layers of metal, where the outer layers are of the same thickness and material and different from those of the inner layer. In this study, a new deformation model has been introduced in which inlet and ou...
