Glass　materials　are　extensively　used　in　load-bearing　structures　and　impact-resistant　components　because　of　their　distinctive　physical　and　chemical　properties.　Accurate　predictions　and　assessment　of　the　mechanical　responses　of　glass　structures　are　crucial　for　structural　design　and　reliability　analysis.　In　this　study,　quasi-static　and　dynamic　ball-on-ring　(BOR)　biaxial　flexural　tests　are　conducted　on　aluminosilicate　glass.　The　smeared　fixed　crack　model　is　calibrated　for　deformation　and　failure　analyses.　First,　the　model　parameters　are　calibrated　carefully,　particularly　for　different　failure　criteria.　Both　the　deformation　field　and　fracture　modes　agree　well　with　the　experimental　observations　during　the　quasi-static　tests.　For　the　low-velocity　impact　biaxial　flexural　loading　condition,　three　different　numerical　techniques,　namely　the　initial　scaling　tensile　strength　criterion,　non-local　approach　with　energy　criterion,　and　rate-dependent　failure　stress　criterion,　are　implemented　in　the　numerical　models　for　dynamic　failure　analysis.　Finally,　the　proposed　smeared　fixed　crack　model　is　compared　with　the　widely　used　Johnson　Holmquist　II　(JH-2)　model　and　demonstrates　advantages　for　low-velocity　impact　response　analysis　of　glass　structures.
