Multiscale Modeling of Additively Manufactured Metals: Application to Laser Powder Bed Fusion Process

Multiscale Modeling of Laser Powder Bed Fusion: Additive Manufacturing of Metals provides comprehensive coverage of the latest methodology in additive manufacturing (AM) modeling and simulation. Although there are extensive advances within the AM field, challenges to predictive theoretical and computational approaches still hinder the widespread adoption of AM. The book opens with a review of metal additive materials and processes, followed by a discussion of multiscale/multiphysics modeling strategies. In addition, coverage of modeling and simulation of AM process in order to understand the process-structure-property relationship is reviewed, as well as modeling of morphology evolution, phase transformation, and defect formation in AM parts. Residual stress, distortion, plasticity/damage in AM parts are also considered and scales associated with the spatial, temporal, and/or material domains are reviewed. This book is useful for graduate students, engineers and professionals working on AM materials, equipment, process, and development, and modelling. Includes the fundamental principles of Additive manufacturing modeling techniquesPresents various modeling tools/software for AM modellingDiscusses various design methods and how to optimize the AM process using these models INDICE: 1.
