The creep crack growth behavior in a creep-ductile material, 6061 aluminum, and a creep brittle material, Ti-6242, has been investigated. In the creep ductile material an observed load dependency in the relation between the load-point displacement rate, ..delta.., and the crack growth rate, ..cap alpha.., precluded the straightforward application of the C* approach. For both materials tested the foregoing relationship was able to describe the experimental results withoutany systematic scatter.
