Abstract:
Based on the Timoshenko-Mindlin theory, strain energy equivalence hypothesis and Boltzmann super-position principle, the nonlinear creep-damage equilibrium equations of cross-ply laminated cylindrical panels subjected to an axially compressive load are established under considering geometric nonlinearity, transverse shear deformation, damage effect and initial imperfection. The damage evolution equation proposed by Kachanov is taken, but considering the tension and compression have different contribution to the rate of the material's damage evolution. In the numerical calculations, the influences of various parameters including transverse shear deformation, geometric parameter and number of layers on the creep postbuckling behavior of damage/viscoelastic laminated cylindrical panels and damage evolution property are discussed in detail.
