Does Displaced Mean Dislocation

Dislocations and Plastic Deformation

Dislocations and Plastic Deformation deals with dislocations and plastic deformation, and specifically discusses topics ranging from deformation of single crystals and dislocations in the lattice to the fundamentals of the continuum theory, the properties of point defects in crystals, multiplication of dislocations, and partial dislocations. The effect of lattice defects on the physical properties of metals is also considered. Comprised of nine chapters, this book begins by providing a short and, where possible, precise explanation of dislocation theory. The first six chapters discuss the properties of dislocations and point defects both in crystals and in an elastic continuum. The reader is then introduced to some applications of dislocation theory that show, for instance, the difficulties involved in understanding the hardening of alloys and the work-hardening of pure metals. This book concludes by analyzing the effect of heat treatment on the defect structure in metals. This text will be of interest to students and practitioners in the field of physics.

Displacement Among Sri Lankan Tamil Migrants

This book focuses on the concept of ‘home’ or ‘place of origin’ (expressed in Tamil as ‘Ur’) and its various dimensions, in turn related to issues of belonging, attachment, detachment, and commonality among the war-affected population in the post-war era of Sri Lanka. Little research has been undertaken on displacement and forced migration since the end of the war, and so this book provides new insight into the intersections between externally and internally displaced people and notions of home in relation to gender, age, caste and class. It excavates the roots of the problem of not being able to return due to combinations of uncertainty, unemployment, and the loss of people and property. The author shows that notions of ‘home’ vary considerably depending on multiple variables, and this is particularly pronounced between the different generations. The book also confronts how the migration from Sri Lanka over the border to India has brought on discernible changes to the lives of women in particular, in transforming their identities in multiple re-invented cultural manifestations, and cultivating a new kind of attachment towards their new homes. Interdisciplinary in tenor, this book will be of interest to scholars in development studies with a focus on South Asia, as well as graduate students and researchers in the fields of migration, conflict studies, Sri Lanka studies, and sociology. It may also have an impact on policymakers owing to its comprehensive, empirically-based analysis of the consequences of the Sri Lankan civil war for Tamils.
