ASME Boiler and Pressure Vessel Code Section VIII Division 1 [1] is one of the most commonly used pressure vessel codes in the world. The Division 1 rules were originally written before the age of computers; they were intended to be solved by simple hand calculations. This simplification led to rules with a high safety margin and a conservative technical basis. In 2007, ASME published a complet...

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...

Composite pressure vessels have the characteristics of light weight, corrosion resistance, good sealing, and high reliability, been widely used in military civilian applications. With widespread use composite today, determining how to conduct scientific research correct analysis becomes very important. continuous development computer technology improvement finite element algorithms, numerical c...

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...
