Pressure vessels are used for various industrial applications. To ensure safe operation of pressure vessels, it is important to know its burst pressure. Burst pressure is the pressure at which vessel burst/crack and internal fluid leaks. For light weight application pressure vessel are made of composite material. Payload performance /speed /operating range depends up on weight. Use of composite...

The composite pressure vessels are used in varieties of applications such as automobile, aeronautics and chemical engineering. Besides these, they have become very popular in oil and gas transport industries. These pressure vessels are experience very high internal pressures during their operation. The present paper demonstrates a study on cylindrical section of carbon fiber reinforced polymer ...

In this research, the analytical and numerical investigation of a cylindrical shell made of functionally graded materials (FGMs) reinforced by laminated composite subjected to internal pressure is presented. Using the infinitesimal theory of elasticity, the analytical solution of stress and strain in vessels made of FGMs is studied first. It is assumed that the elasticity modulus follows a powe...

OBJECTIVES We sought to compare patient-oriented outcomes related to target vessel or nontarget vessel events for sirolimus-eluting stents (SES) versus bare-metal stents. BACKGROUND SES significantly reduce restenosis but the influence of reduced restenosis on overall patient-oriented outcome has not been reported. METHODS The study population included 1,057 patients randomized in the SIRIU...

OBJECTIVE To evaluate whether the number of vessels disease has an impact on clinical outcomes as well as on therapeutic results accordingly to medical, percutaneous, or surgery treatment in chronic coronary artery disease. METHODS We evaluated 825 individuals enrolled in MASS study, a randomized study to compare treatment options for single or multivessel coronary artery disease with preserv...

INTRODUCTION There are limited data describing bioresorbable vascular scaffold (BVS) implantation in complex lesions. Only short-term clinical outcomes are available for patients with acute coronary syndrome (ACS). AIM To evaluate 12-month clinical outcome, safety and effectiveness of BVS implantation in complex lesions and in stable angina (SA) or ACS. MATERIAL AND METHODS Five hundred nin...

Nevertheless, in order to respond to the economic and environmental criteria, hydrogen production and storage have to be improved. This work focuses on gaseous storage under high pressure (700 bar) using a type III vessel (figure 1) that is to say composed of a metal liner – which prevents gas diffusion – and of a composite laminate wrapped by filament winding – which is used as a mechanical st...

OBJECTIVES This study sought to investigate the influence of vessel size on the outcomes of patients after drug-eluting stent (DES) implantation. BACKGROUND There are no dedicated studies on the influence of vessel size on the outcomes of patients treated with different DES. METHODS The study population was composed of 2,058 consecutive patients who received sirolimus-eluting stents (SES) o...
