Conservators and other museum professionals face a large number of issues involving the mechanical behavior of materials, including questions on craquelure, restoring physically damaged objects, art in transport, or the selection of adhesives. However, science in conservation and museum studies curricula focusses mostly on chemistry. This book fills this important gap in conservation training. It is the first such book written specifically for the conservation community and professionals with little or no background in (mechanical) engineering. It introduces the basics of mechanical properties and behavior of materials and objects with examples and exercises based on conservation practice. More complex issues of mechanical loading and advanced solutions are also introduced.
