This book aims to bring together continuum elasticity theory， electronic structure and the concept of fractals as applied to roughness and toughness of metals. Of course， a major contribution to fracture was made by Griffith， in which， though incomplete for reasons that are now largely understood， he derived an expression for the limiting strength of a material. This involved intimately the surface energy， which subsequently， at least in a simple metal like A1 with s and p electrons， has been related to the energy of formation of a vacancy. However， a tremendous step forward came with the concept of a dislocation.本書為英文版。
