SOLID MECHANICS AND ITS APPLICATIONS Volume 105 Series editor: GML. GLadWELL University of Waterloo Waterloo, Ontario, Canada n2L 3GI Aims and Scope of the Series The fundamental questions arising in mechanics are: Why ?, How?, and How much The aim of this series is to provide lucid accounts written by authoritative researchers giving vision and insight in answering these questions on the subject of mechanics as it relates to solids The scope of the series covers the entire spectrum of solid mechanics. Thus it includes the foundation of mechanics; variational formulations: computational mechanics statics, kinematics and dynamics of rigid and elastic bodies: vibrations of solids and structures; dynamical systems and chaos: the theories of elasticity, plasticity and viscoelasticity; composite materials; rods, beams, shells and membranes; structural control and stability: soils, rocks and geomechanics; fracture; tribology; experimental mechanics: biomechanics and machine design. The median level of presentation is the first year graduate student. Some texts are mono- graphs defining the current state of the field; others are accessible to final year under graduates; but essentially the emphasis is on readability and clarity For a list of related mechanics titles, see final pagesSOLID MECHANICS AND ITS APPLICATIONS Volume 105 Series Editor: G.M.L.
