説明
Energy release rate of an edge delamination of a laminated beam subject to a through-thickness temperature gradient is analyzed on the basis of the classical beam theory. Further, the decomposition of the energy release rate into mode I and mode II components is made by combining the analyses of the energy release rate of an interfacial crack by Toya (1992) and the two-dimensional linear beam solutions by Suo and Hutchinson (1990). The energy release rate is a quadric function of the temperatures at the top and the bottom surfaces of the layered beam and the mode of delamination growth changes from pure mode II to mixed mode type at the temperature difference at which energy release rate takes minimum value. Assuming several values of Bio number characterizing the heat flow across the delamination surfaces, numerical analyses based on the finite element method are carried out. It is shown that the theory agrees well with numerical analyses if the temperature jump across the crack faces is small (when Bio number is larger than 7).
