A modified model for calculating crack tip opening displacement (CTOD) considering fracture process zone (FPZ) in rock [PDF]

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
A new CTOD calculation method is investigated in this study, considering the FPZ and the effective Young’s modulus. The calculated CTOD values from four theoretical models are compared with the measured CTOD values from the three-point beam experiments ...
