In this work the current developments on the numerical simulation of
different AM processes are presented. A fully coupled thermo-mechanical
framework has been tailored to the analysis of several 3D-printing
processes ranging from metal or polymers extrusion and melting, to
technologies for civil and architectural applications. The accurate
definition of the material deposition is addressed, taking into account
actual movement of the heat source along the scanning path as defined for
the machine. The result is a high-fidelity simulation of the AM process
leading to an accurate layer-by-layer building sequence. An advanced
high-performance and object-oriented software platform has been enhanced to
include the parallel FE activation technique used to follow the growth of
the geometry according to the fabrication process. The mesh adaptivity
strategy makes use of Cartesian grids together with octree-type local
refinements and global coarsening to keep controlled the total number of
elements in the computational domain. The thermo-viscoelastic-viscoplastic
constitutive model introduced is calibrated and the numerical results are
validated through an extensive experimental campaign carried out taking
advantage of the partnership with several research center such as: the
Northwestern Polytechnical University (Xi’an, China), the Monash and RMIT
Universities (Melbourne, Australia), IK4-Lortek, Leitat, Eurecat (Spain),
among others.
Michele Chiumenti is a Professor of Continuum Mechanics and Structural
Analysis at the Department of Civil and Environmental Engineering at the
Universitat Politècnica de Catalunya (UPC), since 2004. He is also a Full
Professor at the International Center for Numerical Methods in Engineering
(CIMNE) and software developer and product manager (VULCAN software) at
Quantech-ATZ. His work focuses on the finite element technology for highly
non-linear analysis including incompressible limit, strain-localization and
tensile cracking, non-linear constitutive modeling for coupled
thermo-mechanical problems including phase-change and numerical simulation
of metal forming processes for the manufacturing industry such as metal
casting fo foundry processes, EB welding, Additive Manufacturing (AM) by
metal deposition and FRictional Stir Welding (FSW).
Prof. Chiumenti received his Degree in Civil Engineering and MCs from
Politecnico di Milano in 1994 and his Ph.D. degree as Dr. Ingeniero de
Caminos, Canales y Puertos from the UPC in 1999. He is a fellow of the
State Administration of Foreign Experts Affairs of China through the
High-end Experts Recruitment Program and a member of the Spanish Society
for Numerical Methods in Engineering (SEMNI)
