Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 1,   Pages 63-70 doi: 10.1007/s11709-007-0006-2

Abstract: Utilizing the obtained load against crack opening displacement curve, the value of G at any crack extensionas well as the change of G with the crack extension is examined.It is found that G will firstly increase with the development of crack and then stay constant once theinitial crack tip opening displacement reaches the characteristic crack opening displacement w0.The results reveal that the values of G of different specimens at any crack propagation are strongly
