Abstract
Description
CT=(CS・DOL)/(t−2 DOL) (1)
特にことわりがないかぎり、中心張力CTと圧縮応力CSは本明細書ではメガパスカル(MPa)で表され、厚さtと層深度DOLはミリメートルで表される。ガラス成形品に設計上組み込み、または提供できる圧縮層の深度DOLと圧縮応力CSの最大値は破砕挙動、すなわち破壊時のガラスの強力な、または激しい破砕によって限定される。
CTlimit(MPa)=9.0(MPa/mm)・ln(t)(mm)+49.3(MPa/mm)・ln2(t)(mm) (2)
によって決定でき、式中、CTlimitの単位はMPaであり、ガラス厚さtはmmの単位で、約1mmより小さいか、これと等しく、1n(t)は厚さtの自然対数(基数e)である。積分中心張力(ICT)は、張力を受ける全領域(すなわち、図1のd1からd2)について積分された引張応力であり、破砕挙動を特徴付けるために使用してもよい。
SEE=(CT2/E)・(t−2DOL)・(1−ν) (3)
で表され、式中、Eはヤング率であり、tは容器壁の厚さであり、vは材料のポアソン比であり、層深度DOLは、応力が正(圧縮)から負(引張)に変化する深度である。
K1C = Y・σ・(π・c)1/2 (4)
で表され、式中、Yは亀裂形状の幾何学的因子、δは亀裂進展を起こさせるために亀裂に加えられる応力、Cは亀裂の長さである。ガラスの場合、K1Cは約0.7±0.05である。幾何学因子Yは丸型(半ペンス硬貨型)亀裂の場合、約1.12である。亀裂長さcは、ガラス容器の壁厚の約半分と仮定される。厚さ1.1mmの容器壁の場合、CTlimitは、式(4)を使って約15Mpaと算出される。
