Abstract

The results are presented of investigation of the influence of temperature stresses and short-term creep of the material on the critical parameters of time, axial compression, and internal pressure of reinforced cylindrical shells. The initial anisotropy of creep deformations caused by cold hardening of the material is taken into consideration. The critical values of time, temperature, and load in loss of stability of the axially symmetric form of the shell are determined and also of the time, temperature, and load at which occurs replacement of the axially symmetric equilibrium form by a nonaxially symmetric. The calculation results are compared with experimental data on the rigidity of large actual shells.
