PLASTIC ANALYSIS OF RIB-REINFORCED CYLINDRICAL SHELLS

摘要

Using the strain mapping method for the Tresca yield condition, the yield surface is derived for a cylindrical shell with a wall reinforced by longitudinal ribs on one side. Results are given for the case where the axial load is zero. As a sample problem utilizing this surface and an appropriate method of solution of non-linear equations, the exact plastic solution of a cantilever shell under constant pressure is obtained.
