CONTINUUM-BASED STIFFENED COMPOSITE SHELL ELEMENT FOR GEOMETRICALLY NONLINEAR-ANALYSIS Academic Article

abstract

• A continuum-based, laminated, stiffened shell element is used to investigate the static, geometrically nonlinear response of composite shells. The element is developed from a three-dimensional continuum element based on the incremental, total Lagrangian formulation. The Newton-Raphson method or modified Riks method is used to trace the nonlinear equilibrium path. A number of sample problems of unstiffened and stiffened shells are presented to show the accuracy of the present element and to investigate the nonlinear response of laminated composite plates and shells. 1989 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
