In this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. FGM properties and autofrettage pressure are considered as important parameters. Assumptions are variation of properties of FGM in radial direction, the residual stress in the absence of Bauschinger effect with the operation of variable m...

in sheet metal forming processes, one-stage production of conical-cylindrical parts with high accuracy is very difficult due to wrinkling and rupturing. hydrodynamic deep drawing assisted by radial pressure is one of the most applicable procedures in sheet hydroforming process on the point of producing conical-cylindrical parts. in this paper, forming pressure path is investigated as one of the...

The aorta is the most critical blood vessel in our body, and aortic valve between left ventricle (LV) controls flow from heart to whole body. If malfunctions, does not correctly, enough nutrition conveyed all over There so much research on LV aorta; however, of previous works dealt with simplified cylindrical models model. little study simulated pressure change using a real model generated medi...

Background and Objective: Cerebral Arteriovenous Malformation (CAVM) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. Measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in Arteriovenous Malformation patients. The vessel geometry in CAVM patients are...

in this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. fgm properties and autofrettage pressure are considered as important parameters. assumptions are variation of properties of fgm in radial direction, the residual stress in the absence of bauschinger effect with the operation of variable m...

Highly flexible model red cells were molded of acrylamide gel and suspended in a mixture of castor oil and diiodomethane to produce a neutrally buoyant fluid suspension in which the particles behaved mechanically very much like living erythrocytes. The various suspensions were permitted to flow down long cylindrical tubes while measurements of flow rate and pressure drop were made for various c...

In the upstream oil and gas industry Slug Catcher is a separator to separate heavy liquid hydrocarbons gaseous lighter fraction. cylindrical pressure vessel which has horizontal orientation designed with an internal of 84.37 kg/cm2 , 73,89 °C temperature, 3 mm corrosion allowance, 3,500 length, 1,750 diameter. This paper aims design from mechanical side that safe able withstand stress caused by...

Linear eigenvalue analysis of cracked cylindrical shells under combined internal pressure and axial compression is carried out to study the effect of crack type, size and orientation on the buckling behavior of cylindrical thin shells. Two types of crack are considered; through crack and thumbnail crack. Our calculations indicate that depending on the crack type, length, orientation and the int...
