This classic text of elementary dislocation theory has been reprinted to fulfill persistent demand. Because it approaches elementary dislocation theory from its most basic level, the material contained in the volume is as up-to-date as when it was first published. The text addresses many aspects of dislocation theory, including the nature of dislocations, Burgers vectors, motion and its impact on dislocations, internal stresses of dislocations, and multiplication of dislocations. The topics of this text are fundamental to the theory of dislocation behavior. Because dislocation is now widely...

The dislocation is the basic building block of the crack in an elastic-plastic solid. Fracture mechanics is developed in this text from its dislocation foundation. It is the only text to do so. It is written for the graduate student and the new investigator entering the fracture field as well as the experienced scientist who has not used the dislocation approach. The dislocation mechanics needed to find the dislocation density fields of crack tip plastic zones is developed in detail. All known dislocation based solutions are given for the three types of cracks in elastic-plastic solids.
