Deformations of pressure vessel domes in asymmetric winding
- 34 Downloads
The deformation of pressure vessel domes in asymmetric winding with the use of two families of yarns is accompanied by shear deformations and torsion. For the case of large deformations, a system of equations for describing the stress-strain state of an asymmetrically reinforced netlike shell of revolution loaded with an internal pressure is obtained. It is shown that the shear deformations depend on the deformations of both the yarn families and the deformations of meridians and parallels of the shell. As an example, the dome of a pressure vessel in a deformed state is calculated for an initial equilibrium shape determined on the assumption that the yarns are inextensible.
