Penurkar/ Structural Integrity Procedia 00 (2023) 000 – 000 5 After obtaining the maximum load at fracture, bending stress ( ) required for fracture of the glass specimen is evaluated as shown in Eq. (1). = (1) where, = 1 4 (2) = 1 6 2 (3) where is the maximum bending moment, is section modulus of cross section of the specimen, is the span of the attachment, is the maximum load required for the glass to break, is the width of the specimen, is the thickness of the specimen. 359
