Hybrid Finite Element Method for Stress Analysis of Laminated Composites presents the development of the partial hybrid finite element method for the stress analysis of laminated composite structures. The authors believe that the partial hybrid finite element method is more efficient than the displacement-based finite element method for the stress analysis of laminated composites. Since there is a great need for accurate and efficient calculation of interlaminar stresses for designs using composites, the partial hybrid finite method does provide one possible solution.
Hybrid Finite Element Method for Stress Analysis of Laminated Composites is the culmination of the work of three generations of PhD students in the Concordia Center for Composites. Particular points of interest include:
• a new ISO function method and classification of stress modes which allow the systematic determination of stress polynomials
• how the hybrid finite elements and global/local approach allow the stress analysis of laminated composites to be five times more efficient than the displacement finite element method
• a detailed description of three different types of hybrid finite elements for laminated composites.
Hybrid Finite Element Method for Stress Analysis of Laminated Composites will be of interest to researchers and designers of laminated composites as well as finite element method students and programmers of finite element codes.
