The Influence of Temperature on Crack Growth in Fibre Metal Laminates

A robust crack growth prediction tool has been developed for a class of
hybrid skin materials known as Fibre Metal Laminates (FMLs) which has been
thoroughly validated for fatigue loading cases at room temperature. This paper
provides a brief overview of this predictive model and presents an investigation
into its predictive capabilities at various temperatures. Amongst the temperature
effects investigated are crack growth rate in the metal layers, delamination growth
rate along the metal-fibre interfaces, and residual curing stresses within the
laminate. Results from this investigation indicate that the present model
accounting for these effects can accurately predict crack growth in FMLs at room
temperature and elevated temperature, but is overly conservative for predictions at
low temperatures.
