Static Buckling of FML Columns in Elastic-Plastic Range

The paper deals with the elasto{plastic buckling of thin-walled Fiber Metal Laminates short columns/pro les subjected to axial uniform compression. Structures of open and hollow (closed) cross-sections are considered build of at plate walls. Multilayered FML walls are considered as built of alternating layers of aluminum and fiber-glass composite. Three elastic{plastic theories are employed for constitutive relations description of aluminum layers i.e. fully elastic material behavior, the J2-deformation theory of plasticity and the J2-flow theory later both with Ramberg-Osgood formula application, whereas composite layers are assumed elastic within whole loading range. Some exemplary results determined with the application of own analytical-numerical method based on the Koiter's theory, in the Byskov and Hutchinson formulation are enclosed in the form of tables and plots.
