Recrystallization and Related Annealing Phenomena
F.J. Humphreys,M. Hatherly +1 more
TL;DR: In this paper, the authors discuss the extent to which we are able to formulate quantitative, physically-based models which can be applied to metal-forming processes, and the subjects treated in this book are all active research areas and form a major part of at least four regular international conference series.

Roark's Formulas for Stress and Strain
TL;DR: This chapter discusses the Behavior of Bodies Under Stress, which involves tension, Compression, Shear, and Combined Stress, and the role of Fasteners and Joints in this Behavior.
Journal ArticleDOI
Consolidation phenomena in laser and powder-bed based layered manufacturing
TL;DR: In this article, the authors describe which types of laser-induced consolidation can be applied to what type of material, and demonstrate that although SLS/SLM can process polymers, metals, ceramics and composites, quite some limitations and problems cause the palette of applicable materials still to be limited.

Journal ArticleDOI
Residual stress and its role in failure
TL;DR: In this article, the origins of residual stress are understood, opportunities for removing harmful or introducing beneficial residual stresses recognized, their evolution in-service predicted, their influence on failure processes understood and safe structural integrity assessments made, so as to either remove the part prior to failure, or to take corrective action to extend life.
