Determination of the material model parameters for high pressure densification induced glass inferred through analytical comparison and its ballistic performance as used in composite laminates

Abstract

Abstract The Drucker Prager material model, Ductile Damage and Mie-Gruneisen equation of state parameters for high-pressure densification induced glass were derived analytically in the current study by comparing them to the Johnson Holmquist-II (JH-2) model. These parameters were then utilized to simulate the ballistic impact behaviour of bullet-resistant glass in ABAQUS/Explicit and the results were compared to the simulation results using JH-2 model in ANSYS/Autodyn and the results were found in good agreement. Following that, their experimental equivalents were tested for validation prospective. The findings were then compared to conventional bullet-resistant glass. It was found that the new bullet-resistant glass fabricated from layers of high-pressure densification induced glass was superior in strength as compared to the conventional bullet-resistant glass.
