Fracture energy - Garwood method?

Mai Lan NGUYEN's picture

Anyone know the Garwood method which is used to determine the fracture energy of concrete (composite materials)?

Garwood method: with a load - load line displacement curve of an three point bending fracture test (or SENB), we have firstly:


After, an iterative relation is used:


B,H : width and height of the beam respectively.

a : crack length 


In fact, it's not clear the determination of the initial value Jo

Please tell me references for this method.

Thank you very much for yours helps
