Modelisation de structures composites par elements finis de coque degeneres
Keywords:
Finite element, shells, modelisation, composite materials, buckling, critical loads, vibration testsAbstract
Due to the increased use of composite materials in industrial applications, reliable and efficient finite element methods are needed for the analysis and design of composite structures. This paper deals with the extension of the formulation of the three-D degenerated shell element based on the Mindlin theory for the analysis of static, linear buckling and free vibrations problems of composite and sandwich structures. The shell element has 5 nodes and 40 degrees of freedom. Numerical results obtained for benchmark and real tests are presented and compared showing the validity of the present shell element.
