[en] The concept of partial thickness method developed by Marcal and King (1967) has been used for elasto-plastic analysis of plane stress/plane strain and axisymmetric bodies by finite element method. A computer algorithm developed on the above basis has been checked by solving three typical problems, namely, elastic-plastic deformation of: (1) a thick cylindrical shell, (2) perforated tension strip under inplane loa.ding, and (3) notched tension strip. The results have been compared with other known solutions/experimental results. (M.G.B.)
