Book excerpt: In the thesis, a combined experimental and stochastic finite element analysis methodology that can incorporate the material property variabilities and based on these, predict the stochastic characteristics of the Stress Intensity Factor (SIF) and the Strain Energy Release Rate (G) of composite laminates, is developed. Using this methodology, the probabilistic fracture analysis of laminated composites is performed. The material and geometric properties of the laminate are described in terms of homogeneous two-dimensional spatial stochastic fields and random variables that are established based on material property tests. In the finite element formulation, the elasticity matrix for the laminate is obtained based on the laminate theory. This matrix, in contrast to the deterministic finite element analysis, will be a stochastic matrix that has different values at different Gauss point locations within the same element. The fracture behavior of the laminate is quantified through the two parameters, Stress Intensity Factor (SIF) and Energy Release Rate (ERR). A formulation for determining the reliability of composite laminates based on the probabilistic characteristics of stress intensity factor and that of the fracture toughness, is described. Different types of orthotropic laminates are analyzed.

Download or read book Finite Element Analysis of Composite Laminates written by O.O. Ochoa and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composite materials are increasingly used in aerospace, underwater, and automotive structures. To take advantage of the full potential of composite materials, structural analysts and designers must have accurate mathematical models and design methods at their disposal. The objective of this monograph is to present the laminated plate theories and their finite element models to study the deformation, strength and failure of composite structures. Emphasis is placed on engineering aspects, such as the analytical descriptions, effective analysis tools, modeling of physical features, and evaluation of approaches used to formulate and predict the response of composite structures. The first chapter presents an overview of the text. Chapter 2 is devoted to the introduction of the definitions and terminology used in composite materials and structures. Anisotropic constitutive relations and Iaminate plate theories are also reviewed. Finite element models of laminated composite plates are presented in Chapter 3. Numerical evaluation of element coefficient matrices, post-computation of strains and stresses, and sample examples of laminated plates in bending and vibration are discussed. Chapter 4 introduces damage and failure criteria in composite laminates. Finally, Chapter 5 is dedicated to case studies involving various aspects and types of composite structures. Joints, cutouts, woven composites, environmental effects, postbuckling response and failure of composite laminates are discussed by considering specific examples.

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work concerns the stochastic mechanics and reliability of composite laminates. The reliability of notched composite laminates is evaluated based on the average stress over a certain characteristic distance from the notch edge and the strength of the corresponding un-notched laminate. In the present work the perturbation in the radius of the hole is modeled using a hypotrochoid variation and further, the location of the hole centre is modeled using a Gaussian random variable. In order to achieve a design with a required reliability and safety, (i) the stress analysis of the notched laminate has to be conducted based on a stochastic approach, (ii) the strength distribution and its probabilistic parameters have to be determined based on a number of tests, and (iii) the reliability analysis has to be conducted. Two-dimensional stochastic finite element analyses of notched symmetric cross-ply [0/90] 4 s and angle-ply [02/±45] 2 s composite laminates are conducted. A comprehensive experimental investigation is carried out to determine the strength values of the laminates subjected to tensile load. Average stress criterion is used to predict the characteristic length values of the laminates. The distributions of the strength and characteristic length of laminates with symmetric cross-ply [0/90] 4 s configuration are determined by testing 25 samples of notched and 25 samples of un-notched laminates. In a similar manner, tests on angle-ply laminate [02/±45] 2 s are conducted. Stochastic simulation is performed on the laminates by subjecting them to uniaxial, biaxial, shear and bending loads. Probabilistic moments of the stress parameters that are of interest are found out for the so-called controlled hole and uncontrolled hole laminates. The reliability indices for the two laminate configurations are calculated by combining the stochastic finite element analysis and the test results.

Book Synopsis Hybrid Finite Element Method for Stress Analysis of Laminated Composites by : Suong Van Hoa
Download or read book Hybrid Finite Element Method for Stress Analysis of Laminated Composites written by Suong Van Hoa and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has one single purpose: to present the development of the partial hybrid finite element method for the stress analysis of laminated composite structures. The reason for this presentation is because the authors believe that partial hybrid finite element method is more efficient that the displacement based finite element method for the stress analysis oflaminated composites. In fact, the examples in chapter 5 of this book show that the partial hybrid finite element method is about 5 times more efficient than the displacement based finite element method. Since there is a great need for accurate and efficient calculation of interlaminar stresses for the design using composites, the partial hybrid finite method does provide one possible solution. Hybrid finite method has been in existence since 1964 and a significant amount of work has been done on the topic. However, the authors are not aware of any systematic piece of literature that gives a detailed presentation of the method. Chapters of the displacement finite element method and the evolution 1 and 2 present a sununary of the hybrid finite element method. Hopefully, these two chapters can provide the readers with an appreciation for the difference between the displacement finite element method and the hybrid finite element. It also should prepare the readers for the introduction of partial hybrid finite element method presented in chapter 3.
