 note = {This paper presents a fracture mechanics approach to the delamination of laminated beams by three-and four-point bending. Interlaminar cracking is assumed to develop from both sides of a bonded beam. Based on the Euler-Bernoulli beam theory (elementary beam theory), the compliance and the total energy release rate are derived, and the stability of the delamination process is discussed. Finite-element computations are then performed to evaluate the compliance and the mode I and II energy release rates. Numerical results are shown to agree well with those based on the elementary beam theory. Finally, through the analysis of the J-integral for the interlaminar crack, it is concluded that the ratio of the mode I to mode II energy release rate is nearly independent of cracking length.},
