Fracture energy of concrete: Method of determination
(1980) In Cement and Concrete Research 10(1). p.78-89- Abstract
- When the maximum load at a three-point bend test on a notched beam is known, Gc can be estimated from a well-known method of linear elastic fracture mechanics. The method, in this case called the indirect method, has proved to be unsuitable for use in Gc-determinations of concrete-like materials. The method is too dependent on the specimen size.
Another method of directly determining Gc is also dealt with. A three-point bend test on a notched beam gives a stable load-deflection curve. The area under the curve represents the amount of energy consumed when the crack propagates through the beam. When the cross-sectional area is known, Gc can be calculated. Results and calculations in this paper imply that this method is...
