چکیده انگلیسی
This paper presents the application of the isoparametric spline finite strip method to the geometric nonlinear analysis of perforated folded-plate structures. The general theory of the isoparametric spline finite strip method is introduced. Kinematics, strain–displacements and constitutive assumptions are described and applied to the spline finite strip method. The derivation of the tangential and secant stiffness matrices is presented by applying the equilibrium condition and its incremental form. The reliability of the method is demonstrated by applying the method to classical nonlinear complex plate and shell problems as well as the geometric nonlinear analysis of perforated flat and stiffened plates.
