Abstract

Constrained deformation of materials is a ubiquitous phenomenon in the engineering world. In a majority of situations it creates real problems that limit the performance of materials and devices and generate reliability concerns; in others the problem is actually induced by design for the purpose of achieving specific functionalities. In previous chapters we have treated thermo-mechanical deformation influenced by physical constraint due to the outside media bonded to the material or the internal material heterogeneities. Attempts were made to establish a unified theme encompassing past developments as well as new analyses. The deformation characteristics were addressed from a continuum modeling point of view, without elaboration on the attributes of microstructural details (molecular configuration, crystal structure, grain size, texture, crystal defect density, defect interaction etc.). Although this is a simplified way to deal with the overwhelmingly complex problem spanning a wide range of length scales, it serves the critical purpose of facilitating a mechanistic framework for basic understanding, which is frequently lacking even in the research community. It goes without saying that, in real-life engineering design and analysis, only the simple approach matters.
