A 3-D geometrically and physically nonlinear problem of elastoplastic
deformation, loss of stability, and supercritical behaviour of a cylindrical shell with discrete
aggregate loaded in bending is analyzed. The numerical analysis of the problem is based
on the FEM and an explicit cross-type time integration scheme. The results of the
analysis are compared with the experimental data.
Keywords: thin-walled cylindrical shell; in bending; nonlinear problem; elastoplastic deformation; loss of stability.
