TL;DR: In this article, the conservative level set method for incompressible two-phase flow with surface tension is studied. But the authors focus on the conservation of mass and do not consider the effect of the finite element discretization.

TL;DR: In this paper, a combination of high strength and high ductility produced in metals subject to severe plastic deformation (SPD) was shown to enable deformation by newmechanisms.
Abstract: It is well known that plastic deformation induced by conventional forming methodssuch as rolling, drawing or extrusion can significantly increase the strength of metalsHowever, this increase is usually accompanied by a loss of ductility. For example, Fig.1 shows that with increasing plastic deformation, the yield strength of Cu and Almonotonically increases while their elongation to failure (ductility) decreases. Thesame trend is also true for other metals and alloys. Here we report an extraordinarycombination of high strength and high ductility produced in metals subject to severeplastic deformation (SPD). We believe that this unusual mechanical behavior is causedby the unique nanostructures generated by SPD processing. The combination ofultrafine grain size and high-density dislocations appears to enable deformation by newmechanisms. This work demonstrates the possibility of tailoring the microstructures ofmetals and alloys by SPD to obtain both high strength and high ductility. Materialswith such desirable mechanical properties are very attractive for advanced structuralapplications.

TL;DR: In this paper, a model for the shear modulus and yield strength as functions of equivalent plastic strain, pressure, and internal energy (temperature) was presented for high-strain rate.
Abstract: A model, applicable at high‐strain rate, is presented for the shear modulus and yield strength as functions of equivalent plastic strain, pressure, and internal energy (temperature) The parameters needed to implement the model have been determined for 14 metals Using this model, hydrodynamic computer simulations have been successful in reproducing measured stress and free‐surface‐velocity–vs–time data for a number of shock‐wave experiments
