| description | In this study, the dynamic mechanical properties, damage and failure mechanisms of high borosilicate glass were investigated from macro to micro perspectives through experiments, simulations and theoretical analysis. The results indicate a notable enhancement in the strength of high borosilicate glass with rising strain rates, accompanied by a gradual decline in failure strain. Due to the inertia effects and micro-scale deformation mechanisms, the strain rate dependency coefficient of glass exhibits a significantly lower strain rate dependency coefficient compared to typical crystalline materials. As the strain rate increases, there is a gradual increase in the total number of fractured particles, accompanied by a decrease in the average diameter. The DID model, which considers both the strain rate and the initial crack distribution, provides a better prediction of particle size. Upon examining cross-sections of particles, it is evident that most fractures are flat and smooth, exhibiting river-like texture and transverse fine heckle lines. The rise in the occurrence of irregular bulges and heckle lines enhances the energy absorption of the material, resulting in a strain rate effect on strength at the macroscopic level. This fundamental distinction sets high borosilicate glass apart from typical crystalline materials. |
