Fall-induced hip fracture is an epidemic health risk among elderly people. This book presents an image-based multilevel modeling approach to understanding the biomechanics involved in fall-induced hip fracture. By hierarchically integrating a body-level dynamics model, a femur-level finite element model, and a local bone failure model, the biomechanics approach is able to simulate all stages in sideways falls and to incorporate all biomechanical variables affecting hip fracture. This book is useful for clinicians to accurately evaluate fracture risk, for biomechanical engineers to virtually test hip protective devices, and for biomedical students to learn image-based biomechanical modeling techniques. This book also covers: Biomechanical viewing on bone composition, bone remodeling, and bone strength Bone imaging and information captured for constructing biomechanical models Bone mechanical testing and mechanical properties required for biomechanical modeling

In this monograph, the origin of shear locking was tried to be explained clearly. Factors which might have significant effects on shear locking were analyzed. These factors mainly include interpolation order, integration scheme and selection of variational principle. Later, a general solution, called field consistence approach, was put forward, which was applied in explaining shear locking and in developing highly efficient beam elements. Then, the field consistence approach was used, in an indirect way, in deriving a 3-node triangular and a 4-node quadrilateral plate bending element. Finally, some of the developed shear-flexible elements were extended, with the aid of a co-rotational formulation, to accommodate finite rotation, to check their efficiency in non-linear situations.
