    Abstract

    In cases of linear-elastic material behavior the parameter N of subcritical crack growth is often determined by dynamic bending tests with different loading rates. At high temperatures the obtained results are influenced by creep effects. A procedure is described to evaluate N under creep conditions by correction of bending strength and loading rate.
