Book Description
Analytical methods are developed for determining deflection of composite beams under transverse load with various boundary conditions and laminate configurations. The present methods include development of expression for 1-D equivalent bending stiffness with and without presence of twisting curvature and prediction of the beam deflection accounting for transverse shear effect. Finite element analysis of 3-D ANSYS models is conducted by using Solid186 elements. The present analytical model is executed by using MATLAB program. Both analytical and FEM models were first validated by using isotropic material in the model and comparing the existing solutions. The composite beams with rectangular cross-section and small ratios of its length to its width and its width to its depth were selected for study. These conditions were chosen for enhancing the effect of the shear deformation. Various boundary conditions used for study include simply support, fixed at both ends, and cantilever beams under uniformly distributed or concentrated load, respectively. The maximum deflection of composite beams is investigated for transverse shear effects due to laminates with symmetric vs unsymmetrical layups and balanced vs unbalanced layups. Among all of the case studies, the analytical results agree well with the results obtained from FEM. It is found that for a given laminated beam under the same type of loading, effect of transverse shear on beam deflection is identical regardless with simply supported and fixed both ends but more pronounced for the case of cantilever beam. However, the effect of shear deformation on beam deflection due to stacking sequence is insignificant regardless of the type of loading.

Book Description
Most books on the theory and analysis of beams and plates deal with the classical (Euler-Bernoulli/Kirchoff) theories but few include shear deformation theories in detail. The classical beam/plate theory is not adequate in providing accurate bending, buckling, and vibration results when the thickness-to-length ratio of the beam/plate is relatively large. This is because the effect of transverse shear strains, neglected in the classical theory, becomes significant in deep beams and thick plates. This book illustrates how shear deformation theories provide accurate solutions compared to the classical theory. Equations governing shear deformation theories are typically more complicated than those of the classical theory. Hence it is desirable to have exact relationships between solutions of the classical theory and shear deformation theories so that whenever classical theory solutions are available, the corresponding solutions of shear deformation theories can be readily obtained. Such relationships not only furnish benchmark solutions of shear deformation theories but also provide insight into the significance of shear deformation on the response. The relationships for beams and plates have been developed by many authors over the last several years. The goal of this monograph is to bring together these relationships for beams and plates in a single volume. The book is divided into two parts. Following the introduction, Part 1 consists of Chapters 2 to 5 dealing with beams, and Part 2 consists of Chapters 6 to 13 covering plates. Problems are included at the end of each chapter to use, extend, and develop new relationships.
