Cylindrical stress field

WebThe analysis of a thin-walled internally-pressurised cylindrical vessel is similar to that of the spherical vessel. The main difference is that the cylinder has three different principal stress values, the circumferential stress, the radial stress, and the longitudinal stress l, which acts in the direction of the cylinder axis, Fig. 7.3.9. WebGeneral finite element (F.E.) coupled transient-dynamic model of three layers cylinder in polar coordinates under stress plane assumption, will be introduced and discussed.
