Study of burst pressure calculation method of pipelines with axial flaws;

The burst pressure of filament wound pressure vessels and the ratio of strength transfer of fiber;

The prediction of the burst pressure of pressure vessels with miter pipe

On the basis of the test results of a full scale hot state explosion test a calculation and analysis was conducted of the explosion pressure of the following: square box test parts, nodular cast iron boiler, grey cast iron boiler and grey cast iron boiler plates.

In this article, the influence of thickness reduction due to big deformation for bursting pressure of multilayered cylinder & spherical shells is analyzed.

By using mathematic model and Tresca yield criteria the total yield pressure and bursting pressure of flat ribbon-wound pressure vessel were discussed,the simple calculation formula for bursting pressure of flat ribbon-wound pressure vessel was given,the certification of practical example calculation was made for the accuracy and fineness of the calculated value.

Based on that mechanism, the calculation formula for bursting pressure is derived.
