abstract

in this paper, an experimental and numerical investigation into the effect of the hoop welding in metallic pressure vessel is presented. in the experimental manufacturing, hoop welding was used to attach the cylindrical body of the vessel, and the effect of welding into stress and strain distribution is carried out. experimental strains are obtained by using the strain gauges attached to predetermined places and stresses calculated by using hook’s law in composite materials. the results of the two methods are compared with each other.

Acoustic Emission Inspection of Spherical Metallic Pressure Vessels

Non destructive evaluation of metallic, spherical pressure vessels is crucial to the safety and operations of a plant due to the large volume of hazardous products stored at high pressures. Sizes of such spheres vary and diameters may range from 10 to 25 meters, even more, while total length of welds can be hundreds of meters. Additionally, accessibility for inspection is often limited, as is t...

Effect of Material Gradient on Stresses of Thick FGM Spherical Pressure Vessels with Exponentially-Varying Properties

Using the Frobenius series method (FSM), an analytical solution is developed to obtain mechanical stresses of thick spherical pressure vessels made of functionally graded materials (FGMs). The cylinder pressure vessel is subjected to uniform internal pressure. The modulus of elasticity is graded along the radial direction according to power functions of the radial direction. It is assumed that ...
