Creep stability of anisotropic shallow spherical shells with account for transverse shear strains

  • Published:
Polymer Mechanics Aims and scope

Abstract

The deformation properties of glass-reinforced plastics are approximated by the relations for a homogeneous anisotropic material, only the shear creep strains being taken into account, since the normal forces, coinciding with the direction of the reinforcement, produce much less creep. Deflections commensurable with the thickness of the shell are considered (geometric nonlinearity), but the strain components are assumed small. The nonlinear relations obtained for this problem have been solved (for a particular case) on a computer. At loads less than the long-time critical value the growth of deflections in time is damped; at large loads the rate of growth of deflections increases.
