Dynamic plasticity and fracture in high density polycrystals: constitutive modeling and numerical simulation

“…Spallation (material separation due to tensile wave propagation) has been observed in plane shock wave experiments on this material (Dandekar and Weisgerber, 1999). Macroscopic constitutive models (Stevens and Batra, 1998;Wei et al, 2001;Yadav et al, 2001) typically used to represent the two-phase system in numerical simulations currently lack a rigorous description of the kinematics of anisotropic plasticity (e.g. plastic spin), the role of crystallographic orientation of constituent grains, and the effects of crystal morphology on failure processes.…”

Modeling dynamic plasticity and spall fracture in high density polycrystalline alloys

“…Stevens and Batra, 1998;Wei et al, 2001) previously used to represent the two-phase system in numerical simulations lack a rigorous description of the kinematics of anisotropic plasticity (e.g. plastic spin), the role of lattice orientations of constituent grains, and the effects of crystal morphology on failure processes.…”

Adiabatic Shear: Pre- and Post-Critical Dynamic Plasticity Modelling and Study of Impact Penetration. Heat Generation in this Context

“…Stevens & Batra, 1998, Martinez et al, 2007 and high speed machining (see e.g. Molinari et al, 2002, Burns & Davies, 2002 with the predominant failure mechanism triggered by adiabatic shear banding (ASB), a threedimensional insight and treatment are desirable.…”
