Within the present work, the effect of material nonlinearity and inelastic behavior on the dynamic response (including spallation) of soda-lime glass is studied under symmetric flyer-plate loading conditions using computational methods and tools. Material nonlinearity and deformation irreversibility are modeled in two different ways: (a) as a non-linear elastic material response with no deformation irreversibility; and (b) as a linear-elastic, volumetrically-plastic deformation response. Incorporation of nonlinearity and inelasticity phenomena into a continuum-level material model for soda-lime glass recently developed by the authors revealed that while these phenomena do not measurably affect spall resistance (as measured by a minimum flyer-plate velocity resulting in spallation), they provide beneficial linear-momentum/kinetic energy reduction effects.
