Static and dynamic behaviors of high alkali glass-fibre-reinforced cloth composites

Glass-fiber-reinforced cloth (GFRC) composites have gained wide industrial applications as automotive parts and aircraft components. This work presents an investigation into the static and dynamic mechanical behaviors of the high-alkali GFRC over a wide range of strain rates. Based on a series of experiments, a nonlinear viscoelastic model and a high-pressure equation of state (EOS) are proposed for the compression behavior of the high-alkali GFRC. This is followed by the introduction of a cross-format centered difference scheme. With the implementation of the constitutive model and the EOS, the effects of high-alkali GFRC composites on stress waves are eventually simulated and analyzed.
