... molecular dynamics (MD) simulations to investigate the mechanical and thermal properties at Cu‐Al interface. Design/methodology/approach The two‐temperature model (TTM)‐MD model is used to describe the electron‐phonon scattering at interface of different metals. Before the simulation of heat transfer...

...Arthur Cantarel; Eric Lacoste; Michel Danis; Eric Arquis Purpose To study heat transfer kinetics at the fiber scale in order to describe injection of liquid metal through a fibrous perform initially situated in a preheated mould, which is one of the various methods used in order to produce metal...

... the liquid‐solid transformation of the solidifying metal. The corresponding discretized formulation is solved in the context of a fixed‐mesh finite element method. Numerical results applying this methodology in two cylindrical casting specimens are first presented to assess the influence of different...
