Abstract:

Various open-literature experimental findings pertaining to the ballistic behavior of glass are used to construct a simple, physically based, high strain-rate, high-pressure, large-strain constitutive model for this material. The basic components of the model are constructed in such a way that the model is suitable for direct incorporation into standard commercial transient non-linear dynamics finite-element based software packages like ANSYSAutodyn ANSYSAutodyn version 11.0, User documentation, Century Dynamics Inc. a subsidiary of ANSYS Inc. 2007. or ABAQUSExplicit ABAQUS version 6.7, User documentation Dessault systems, 2007.. To validate the material model, a set of finite element analyses of the Edge-on-Impact EOI tests is carried out and the results compared with their experimental counterparts obtained in the recent work of Strassburger et al. Strassburger E, Patel P, McCauley JW Kovalchick C, Ramesh KT, Templeton DW. High-speed transmission shadowgraphic and dynamic photoelasticity study of stress wave and impact damage propagation in transparent materials and laminates using the edge-on impact method.

Vancouver, Canada November 2005.. Overall a good agreement is found between the computational and the experimental results pertaining to a the front-shapes and propagation velocities of the longitudinal and transverse waves generated in the target during impact b the front-shapes and propagation velocities of the coherent-damage zone a zone surrounding the projectiletarget contact surface which consists of numerous micron- and submicron- size cracks and c the formation of crack centers
