摘要： 易碎玻璃物件具有一旦破裂時抵抗玻璃顆粒彈射的破裂表現。在一些實施例中，易碎玻璃物件可具有玻璃的每單位面積的**彈性壓縮應力能量 的**表面區域、具有玻璃的每單位面積的第二彈性壓縮應力能量 的第二表面區域、及具有單位面積玻璃彈性拉伸應力能量 的一中心區域，其中 。在一些實施例中，易碎玻璃物件可具有包括小於6.5的總載荷比值 ，其中該玻璃的每單位面積的總彈性壓縮應力能量 )小於總載荷 )的60%，且, ， 。在一些實施例中，易碎玻璃物件可具有小於 的微分載荷比值( 。 Frangible glass articles having a fracture behavior that resists ejection of glass particles upon fracture. In some embodiments，the frangible glass articles can have a first surface region with a first elastic compressive stress energy per unit area of glass( )，a second surface region with a second elastic compressive stress energy per unit area of glass ，and a central region with an elastic tensile stress energy per unit area of glass ，where J/㎡. In some embodiments，the frangible glass articles can have a total load ratio less than 6.5及a total elastic compressive stress energy per unit area of glass less than 60% of a total load ，where:, ， ，and. In some embodiments，the frangible glass articles can have a differential load ratio less than. | Frangible glass articles having a fracture behavior that resists ejection of glass particles upon fracture. In some embodiments, the frangible glass articles can have a first surface region with a first elastic compressive stress energy per unit area of glass(Wel comp1 ), a second surface region with a second elastic compressive stress energy per unit area of glass(Wel comp2 ), and a central region with an elastic tensile stress energy per unit area of glass(WT), where (Wel comp1 + Wel comp2 ) - WT ≤ 25 J/m2. In some embodiments, the frangible glass articles can have a total load ratio (Wi/GD) less than 6.5 and a total elastic compressive stress energy per unit area of glass(WC) less than 60% of a total load(Wi), where:WC = Wel comp1 + Wel comp2 , Wi = WC + WT, GD = 4G1C, and G1C = K1C 2 (1-v 2 )/E. In some embodiments, the frangible glass articles can have a differential load ratio(Wd/G1C) less than 72e (-12d1/t) .
