Finite Element Analysis for Composite Structures
This book is an adventure into the computer analysis of three dimensional composite structures using the finite element method (FEM). The text advances gradually from the analysis of simple beams to arbitrary anisotropic and composite plates and shells; it treats both linear and nonlinear behavior. Once the basic philosophy of the method is understood, the reader may expand its application and modify the computer programs to suit particular needs. It is shown how this leads to considerable savings in computer time.
Chapter 1 provides some results from continuum mechanics and forms the Principles of Virtual Work and Potential Energy. Chapter 2 sketches the history of the FEM, particularly in its displacement form. Chapter 3 introduces the concepts of natural modes and natural stiffness. Chapter 4 introduces the basic concepts of the theory of composites. Chapter 5 applies the natural mode method to the analysis of composite beams in three dimensions. Chapter 6 introduces the composite plate and shell element. Chapter 7 show the computational advantages of the method on a model problem. Chapter 8 deals with nonlinear analysis of anisotropic shells. Chapter 9 discusses programming aspects of the technique.
