A time-discontinuous elasto-plasticity formalism to simulate instantaneous plastic flow bursts
Mathias Lamari, Pierre Kerfriden, Oguz Umut Salman +3
Plastic flow is conventionally treated as continuous in finite element (FE) codes, whether in isotropic, anisotropic plasticity, or crystal plasticity. This approach, derived from…
In-situ localization of damage in a Zn-Al-Mg coating deposited on steel by continuous hot-dip galvanizing
Houssem Eddine Chaieb, Vincent Maurel, Kais Ammar +6
Zn-Al-Mg coatings are characterized by a complex microstructure with dendritic and eutectic phases. This heterogeneous phase distribution contributes to multiple deformation and da…
Effect of free surface, oxide and coating layers on rafting in superalloys
Wajih Jbara, Vincent Maurel, Kais Ammar +1
Complex microstructure evolution has been observed \rev{both bare and coated } Ni-based single crystal superalloys. Rafting and depletion are investigated in this study throug…
Multiscale analysis of crystal defect formation in rapid solidification of pure aluminium and aluminium-copper alloys
Tatu Pinomaa, Matti Lindroos, Paul Jreidini +6
Rapid solidification leads to unique microstructural features, where a less studied topic is the formation of various crystalline defects, including high dislocation densities, as…
A Cosserat crystal plasticity and phase field theory for grain boundary migration
Anna Ask, Samuel Forest, Benoit Appolaire +2
The microstructure evolution due to thermomechanical treatment of metals can largely be described by viscoplastic deformation, nucleation and grain growth. These processes take pla…
