The effect of proof over-pressure on pressure vessels structural integrity is analysed. Risk based approach applied using Failure Analysis Diagramme to assess likelihood failure. Special attention paid crack-like defects detected by NDT regular testing which are unacceptable standards, but difficult be repaired. It was show, two examples, that such can remain if some strict conditions fulfilled...
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...
The inspections performed in Davis Besse and the South Texas Project Unit-I reactors pointed out safety issues regarding structural integrity of Pressure Vessel (PV). In these inspections, two anomalies were found: a wall thinning degradation PV upper head reactor small amount residue around instrument-tube penetration nozzles located lower plenum reactor. evolution defects could have resulted ...
