Abstract:Based on Von Karman's nonlinear theory of plate and Kachanov's creep-damage theory, the nonlinear equilibrium equations are established for a rectangle plate with creep and damage, subjected to out-plane and in-plane loads simultaneously and simply supported on four sides. Using the finite-difference method, the equations are solved iteratively. The influence of several factors, such as geometrical nonlinearity and in-place loads, on the creep-damage behavior is discussed.
Keywords:nonlinear theory of plate  creep-damage  finite-difference method
