A multi-criteria h-adaptive finite-element framework for industrial part-scale thermal analysis in additive manufacturing processes
(2022-12)
Article
Open AccessThis work presents an h-adaptive finite-element (FE) strategy to address the numerical simulation of additive manufacturing (AM) of large-scale parts. The wire-arc additive manufacturing is chosen as the demonstrative ... -
Accurate thermal-induced structural failure analysis under incompressible conditions
(Elsevier, 2022-06)
Article
Restricted access - publisher's policyIn this work, the performance of the mixed 3-field displacement/deviatoric-strain/pressure (u/e/p) finite element is examined for nonlinear thermo-mechanical structural applications under incompressible behavior. The ... -
An adaptive Finite Element strategy for the numerical simulation of additive manufacturing processes
(Elsevier, 2021-01)
Article
Open AccessIn this work an adaptive Finite Element strategy to deal with the numerical simulation of Additive Manufacturing (AM) processes is presented. The Selective Laser Melting (SLM) is chosen as the reference technology because ... -
Finite element simulation of additive manufacturing with enhanced accuracy
(Universitat Politècnica de Catalunya, 2022-07-21)
Doctoral thesis
Open AccessThis thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized by multiple ... -
Stress, strain and dissipation accurate 3-field formulation for inelastic isochoric deformation
(2021-09)
Article
Restricted access - publisher's policyThis work exploits the high accuracy of the mixed 3-field u/e/p formulation to address materially non-linear inelastic problems including isochoric deformations. Motivated by the strain-driven format of several constitutive ...
