Abstract:
This paper is concerned with the existence of equilibrium states of a thin-walled hollow
elasto-plastic cylinders fully or partially submerged in a fluid. This problem serves as a
model for many problems with engineering importance. Previous studies on the
deformation of such a shell assumed that the material is linear elastic. This paper takes
into consideration the nonlinear Hollomon materials that (are plastic) can deform
plastically. The effect of gravity on pressure is also taken into account
