Much research in Lagrangian staggered-grid hydrodynamics (SGH) has focused on explicit
viscosity models for adding dissipation to a calculation that has shocks. The explicit viscosity …

Current progress in numerical simulations and machine learning allows one to apply
complex loading conditions for the identification of parameters in plasticity models. This …

In this paper, the mechanical response of ultra fine grained metallic materials under high
strain rate impact conditions is investigated by means of a finite element based numerical …

A new method is presented for modeling contact surfaces in Lagrangian cell-centered
hydrodynamics (CCH). The contact method solves a multi-directional Riemann-like problem …

We propose a new structural model of the mechanical twinning applicable for description of
severe plastic deformation in 2D formulation. The twinning model together with the …

In this study, the effect of sintering temperature on the high strain rate-deformation of 93W-
5.6 Ni-1.4 Fe, 93W-4.67 Ni-2.33 Fe, and 93W-3.5 Ni-3.5 Fe alloys was investigated. The …

A one-dimensional analytical model has been developed for the reverse Taylor anvil-on-rod
impact experiment to provide a method of extracting quantitative information from transient …

Experimental efforts for Taylor-anvil impact tests have often been limited to near room
temperature. The 'Reverse Gun'method proposed by Gust in 1982 allows for the Taylor …
