Fatigue, Fracture Toughness, Fatigue Crack Growth Rate. Fatigue strength of friction stir welded 6082 T4, T6, and T4 -i- 185 °C for 5 h with defect-free welds has been established (Ref 61, 64). The number of cycles to fracture at different stress levels for the T6 and T4 + 185 °C for 5 h conditions is illustrated in Fig. 5.29 (Ref 64). For the postweld heat treated T4 specimens, the number of cycles to failure is slightly below that of T6. This was an unex-... 

Physically based, using detailed thermodynamics and kinetics of phase transformations, cahbrated on direct measurement of micro-structural features and able to predict hardness and strength, with the potential for extension to ductility, fracture toughness, fatigue, and corrosion properties. 

Typical values for the fracture toughness 0 of various adhesives under dilTerent modes of loading are given in the literature [179.180] including fatigue fracture data [180], The references also provide data on work of adhesion for various interfaces and environments. 

Finally, the tapered double cantilever beam specimen [8] described in this study can be effectively used to obtain interface mode-I fracture toughness values under various environmental loadings (e.g., under dry and wet conditions [5,14,15]) and cyclic load conditions (fatigue fracture [7]) these data can be implemented in practical applications to assess the potential growth of a delamination crack at the FRP wood interface.

The fracture surfaces, revealed when the tube is broken open, are found to be smooth with a rippled appearance characteristic of fatigue. This type of behavior is sometimes known as leak before break. On the other hand, if the material lacks toughness, the propagation of the fatigue crack may be intermpted part way through the wall by the intervention of fast fracture, resulting in what is sometimes known as the break before leak mode of failure.
