A new method of crack-tip opening displacement determined based on maximum crack opening displacement

Engineering Fracture Mechanics, 2011
Abstract In this paper a new method is presented to determine the crack-tip opening displacement (CTOD) for the center cracked plate with uniaxial uniform tension load. The maximum crack opening displacement (MCOD) is adopted to estimate CTOD. Based on the series of calculation results by elastic–plastic finite element simulation, an explicit ...

Fiber-optic crack-tip opening displacement sensor for concrete

Cement and Concrete Composites, 1997
Abstract The development of a fiber-optic sensor for embedment in cementitious composites and measurement of displacements associated with the opening of microcracks are described. The sensor can be employed as a transducer for measurement of crack-tip opening displacements during fracture tests.

Crack tip opening displacement estimation formulae for C(T) specimens

Engineering Fracture Mechanics, 2000
Abstract Improved formulae for estimating crack tip opening displacement (CTOD) from test records of compact tension (C(T)) specimens are developed. Two-dimensional, plane strain, finite element analyses of 1T C(T) specimens are made for normalized crack depths, a/W, of 0.40–0.70 using Ramberg–Osgood material behavior with strain hardening ...
