    Notes: A coupled thermomechanical analysis of the Taylor impact test considering flat-ended cylindrical specimens of different materials fired at several striking velocities is presented. To this end, a large strain rate-dependent thermoelasto–plasticity model is used to define the constitutive relationships appearing in the momentum and energy equations both solved in the context of the finite element method. The influence of the strain, temperature, and strain rate effects on the material response is particularly analyzed. The numerical predictions are experimentally validated and compared with results provided by previously reported simulations and simplified analytical expressions. © 2002 American Institute of Physics.

    Notes: A finite element formulation for solving transient multidimensional phase-change problems considering advective effects is presented. This temperature-based formulation includes the definition of a phase-change function able to deal with classical isothermal and non-isothermal phase-change cases. Moreover, a new upwind weight function is defined in order to avoid numerical oscillations in problems with dominant advective effects. Further, some important aspects related to its numerical implementation are also addressed. The ability of this methodology is illustrated, firstly, in the solution of a one-dimensional test example. Finally, the numerical simulation of a direct-chill continuous casting process is performed. © 1998 John Wiley & Sons, Ltd.
