Limiting loads of thin-walled glass-reinforced plastic cylinders in torsion

The article presents the results of an experimental investigation of the regularities of the change of the load-bearing capacity and deformation properties of smooth thin-walled cylinders of glass-reinforced plastic on a phenol formaldehyde binder loaded on the ends by twisting moments at normal and elevated temperature. Integral methods are used for calculating the limiting loads in the case of a temperature field varying over the thickness of the wall. The calculation results are compared with the experimental data.N. E. Joukowski Central Aerohydrodynamic Institute, Moscow Oblast.
