The literature has indicated a growing interest in the field of stress concentration analysis and progressive failure analysis in the pressure vessels. The motivation for this research is to analyze the stress concentration, Stress and failures occurring at the openings of the pressure vessels and the means to reduce the effect of the same. Most of the researchers have worked on the stress concentration, Progressive failures due to crack is shell and optimization of vessel openings under internal pressure. Optimizing a composite pressure vessel demands an objective function. This function must represent the performance of the composite material, and in some cases may have some local minima. Optimizations methods use this objective function to try to find the best solution. In this paper the recent developments, theorie...

Openings in tanks and pressure vessels are necessary to carry on normal operations. Openings are generally made in both vessel shells as well as heads. Unfortunately, these openings also result in penetrations of the pressure restraining boundary, and are seen as discontinuities. Nozzles represent one of the most common causes for stress concentration in pressure vessels and stress concentration factors can be very useful in pressure vessel design. FEM analysis is very efficient method for determination of stress concentration factors; however reliability of FEM analysis should always be assessed. In this paper comparison of the different approaches are done for determining SCF’s for various geometries. The experimental data is taken from previous work done by one of the author. Finite element analysis is carried out using ANSYS comm...

Our design proposes and successfully implements the use of a portable compressor that will supply air to all four tyres via hoses and a rotary joint fixed between the wheel spindle and wheel hub at each wheel. The rotary joints effectively allow air to be channeled to the tyres without the tangling of hoses. With the recent oil price hikes and growing concern of environmental issues, this system addresses a potential improvement in gas mileage; tyre wear reduction; and an increase in handling and tyre performance in diverse conditions.
