Popis: A shear deformation theory is developed to calculate the interlaminar stresses and energy release rate associated with mid-plane edge delamination growth in graphite/epoxy laminates. The analysis includes the effect of residual thermal and moisture stresses. Results indicate that residual thermal stress increases the interlaminar stresses and strain energy release rate, while moisture content tends to alleviate thermal effects. Moreover, the value of moisture content at which the interlaminar stresses and strain energy release rate are totally alleviated is not affected by the stacking sequence.
