Additive manufacturing processes are revolutionizing production throughout the industry. These technologies enable the cost-effective manufacture of small lot parts, rapid repair of damaged components, and construction of previously impossible-to-produce geometries. However, the large thermal gradients inherent in these processes incur large residual stresses and mechanical distortion, which can push the finished component out of engineering tolerance. Costly trial-and-error methods are commonly used for failure mitigation.
However, Finite element modeling provides a compelling alternative, allowing for the prediction of residual stresses and distortion, and thus a tool to investigate methods of failure mitigation prior to building.
If you’re a Professor, Student, or Engineer looking to understand important components in the finite element modeling of additive manufacturing processes, gain an deeper understanding of how the thermal gradients inherent in additive manufacturing induce distortion and residual stresses (and how to mitigate these undesirable phenomena), and learn strategies to improve computational efficiency when simulating various additive manufacturing processes – then there is a book that you may find helpful.
Thermo-Mechanical Modeling of Additive Manufacturing, edited by Autodesk’s own Pan Michelaris and Michael Gouge, serves as an essential reference for engineers and technicians in both industry and academia, performing both research and full-scale production.
This book describes the history and methodology of thermo-mechanical modeling techniques to create accurate and reliable additive manufacturing process simulations.
Provides an in depth introduction to the fundamentals of additive manufacturing modeling, a description of adaptive mesh strategies, a thorough description of thermal losses and a discussion of residual stress and distortion.
Applies the engineering fundamentals to direct energy deposition processes including laser cladding, LENS builds, large electron beam parts and an exploration of residual stress and deformation mitigation strategies.
Concerns the thermo-mechanical modeling of powder bed processes with a description of the heat input model, classical thermo-mechanical modeling, and part scale modeling.
