Technical Paper -
A methodology is proposed in this paper to assess the contribution of residual stresses to the debonding risk in multilayers used as cells for energy conversion at elevated temperature. The conditions of an interface crack extension, given by the Energy Release Rate (ERR) and mode-mixity, are fully investigated for thermal and mechanical loadings. Mode-mixity is calculated from Finite Element...
