Collected in this volume are nineteen selected contributions written by twenty-six scholars in the field, in honour of their teacher and colleague, Professor Joseph Marin. Latest developments in the following specific fields are presented: Mathematical Inference from Mechanics, Elasticity, Cosserat Continua, Elastic Waves, Hypervelocity Impact, Composite Materials, Viscoelasticity, Plasticity, Creep, Relaxation, Low Cycle Fatigue, Crack Formation, Fracture, Pressure Vessel and Extrusion Die Design.The volume is a valuable and original contribution to engineering literature and will be of interest not only to engineers, but also to mathematicians and physicists. Dr. Joseph Marin led a life-long campaign for the introduction of the term Mechanics of the Solid State as a worthy companion of Physics of the Solid State.In fulfillment of his wish and in honour of his memory the present volume has been named Mechanics of the Solid State.It provides a list of the 162 papers and six books contributed by Dr. Marin to engineering literature, and a short description of his professional life.
