Sim-AM 2019 – 2nd International Conference on Simulation for Additive Manufacturing

Additive manufacturing (AM) is evolving as one of the most promising manufacturing technologies for creating solid structures of virtually any shape. Furthermore, AM allows to produce more complex shapes than those obtained through classical manufacturing techniques. As a consequence, applications for AM products range across many fields in engineering, from design models to lightweight components for automotive or aerospace industry, from patient-specific medical implants to civil engineering structural and/or architectural components

All these aspects clearly raise new questions for numerical simulations, computational models and design optimizations of the involved products and processes. While products obtained by innovative design approaches through a real shape and/or topology optimization have the potential to revolutionize the market their design itself is much more complicated than for classic manufacturing techniques. Additionally AM Processes involve multi-physics and multi-scale phenomena. Whereas relevant spatial scales range over many orders of magnitude, important time scales start at microseconds for physical processes and reach to hours or even days. The involved physics often include mechanical, thermal, and phase change problems.

Finally, validation and verification are clearly essential steps to accelerate the transformation of AM into an integrated design to manufacturing tool.

A session dedicated to « Simulation and Fatigue in Metal Additive Manufacturing » is organized by Gianni Nicoletto (University of Parma, Italy) and Nicolas Saintier (ENSAM Paris, France)

Qualification of metal parts produced by additive manufacturing for critical load-bearing applications has to deal with many effects that potentially influence fatigue performance. The effects of surface quality, internal defects, local microstructure heterogeneity and anisotropy and residual stresses can be cited among others. The identification and mechanistic basis of the physical processes leading to crack nucleation and growth across the length scales (from micro to macro) are still major issues in many engineering fields and the establishment of quantitative prediction remains a key research challenge. While experiments provide irreplaceable insight into the link among AM process, material and performance, behavioral models and tools supporting AM part design in fatigue are expected from simulation and modeling activities. This session aims to bring together scientists and engineers addressing fatigue research utilizing experimental and modeling approaches (ideally integrated) including, but not restricted to :

  • AM process – microstructure – fatigue interaction modeling
  • Surface-related fatigue damage modeling
  • Modeling of residual stress effects on fatigue damage and crack growth
  • Multiaxial fatigue life prediction
  • Fatigue crack growth under complex (including non-proportional) loadings
  • Life prediction methodologies for metal AM parts
  • Fatigue of meta-materials and lattice structures
