This　study　presents　a　novel　rate-dependent　bond-based　peridynamic　model　for　predicting　the　mechanical　behavior　of　brittle　aluminosilicate　glass　under　quasi-static　and　dynamic　flexure　loading.　To　achieve　this,　the　damage　criterion　is　modified　with　reference　to　the　concept　of　strain　rate　in　the　classical　continuum　mechanics　(CCM).　Additionally,　a　peridynamic　(PD)　model　with　inhomogeneous　critical　stretch　based　on　the　Weibull　distribution　is　proposed　to　account　for　the　randomly　distributed　defects　in　glass　and　investigate　their　effect　on　crack　initiation　and　propagation.　The　accuracy　and　rationality　of　the　improved　PD　model　are　verified　by　comparing　the　calculated　strength　and　fracture　modes　with　the　experimental　results　under　quasi-static　Ball-On-Ring　(BOR)　and　dynamic　low-velocity　impact　tests.　The　results　show　that　the　rate　effect　increases　the　damage　threshold　of　glass,　enhancing　strength　and　damage　ratio.　Notably,　flexural　failures　induced　by　tensile　stress　are　observed　under　both　static　and　dynamic　loading.　The　rate-dependent　inhomogeneous　PD　model　indicates　that　glass　inhomogeneity　reduces　strength　while　increasing　crack　propagation　velocity　(CPV).　The　introduction　of　pre-existing　defects　alters　the　symmetrical　crack　propagation　pattern　typically　observed　in　homogeneous　materials,　resulting　in　a　more　randomized　crack　propagation　path.　Overall,　the　results　can　provide　a　promising　approach　for　predicting　the　mechanical　behavior　of　brittle　materials.
