NUMERICAL ANALYSIS OF CRITICAL PRESSURE IN THE THIN-WALLED CYLINDRICAL SHELL CONTAINING A SOFT LAYERV.L. Dil'man
The numerical analysis of critical pressure in thin-walled cylindrical shells with use of author's mathematical models of the stress-strained state of such shells is made at a loading their intrinsic pressure and an axial thrust. It is supposed, that shells contain layers from less strong material. On the basis of these models the programs are created, allowing to find a critical intrinsic pressure in shell depending on mechanical and geometrical parameters and conditions of loading. Full text
