The study presents theory of layered axially compressed cylindrical rods (shells with a core). The author analysed problems of critical loads in elasto-plastic states. The plasticity ratio of a critical transverse section was defined by the angleα , and was related to the slenderness ratio of rods. The obtained theoretical results were compared with the experimental results of rods made of R35 steel (Standard PN-73/H-74240).
