Book Description
A three-dimensional (3-D) finite element model for concrete pavements, called 3DPAVE, was developed in this study in order to analyze accurately the many complex and interacting factors which influence the support provided to a concrete pavement. Pavement support and finite element models for pavements were first briefly reviewed. Based on the review, the ABAQUS general-purpose finite element software was used to develop a powerful and versatile 3-D model to overcome many of the inherent limitations of 2-D finite element models. A careful analysis of ABAQUS' many element types, features and options was conducted to select the components which would produce a robust and efficient model. The 3DPAVE consistently outperformed the 2-D model in accuracy over wide ranges of inputs for a variety of problems during its development. 3DPAVE was validated by comparison with measured deflection, stress, and strain data for traffic loading and temperature variation from AASHO Road Test, the Arlington Road Test, and the Portland Cement Association's slab experiments. In every comparison with measured field data, 3DPAVE's calculated responses were found to be in very good agreement with the measured responses. Applications of 3DPAVE were made to explore many complicated effects and interactions in concrete pavements, including foundation support; base thickness, stiffness, and interface bond/friction; slab curling and warping due to temperature and moisture gradients; dowel and aggregate interlock load transfer action at joints; and improved support with a widened lane, widened base, or tied concrete shoulder.

Book Description
Though many 'finite element' books exist, this book provides a unique focus on developing the method for three-dimensional, industrial problems. This is significant as many methods which work well for small applications fail for large scale problems, which generally: are not so well posed introduce stringent computer time conditions require robust solution techniques. Starting from sound continuum mechanics principles, derivation in this book focuses only on proven methods. Coverage of all different aspects of linear and nonlinear thermal mechanical problems in solids are described, thereby avoiding distracting the reader with extraneous solutions paths. Emphasis is put on consistent representation and includes the examination of topics which are not frequently found in other texts, such as cyclic symmetry, rigid body motion and nonlinear multiple point constraints. Advanced material formulations include anisotropic hyperelasticity, large strain multiplicative viscoplasticity and single crystal viscoplasticity. Finally, the methods described in the book are implemented in the finite element software CalculiX, which is freely available (www.calculix.de; the GNU General Public License applies). Suited to industry practitioners and academic researchers alike, The Finite Element Method for Three-Dimensional Thermomechanical Applications expertly bridges the gap between continuum mechanics and the finite element method.
