    Abstract

    Examples are given where influence of residual stress leads to erroneous interpretation of fatigue crack growth rate measurements made in accordance with ASTM Method E 647-78T. The experimental data presented form a basis for modification of applicable ASTM documents to give recognition to problems caused by residual stress, and to suggest guidelines for minimization of their effect on fracture property measurement.

    Keywords:

    residual stress, fracture mechanics, fatigue, fatigue crack growth, test methods (metals), mechanical properties (metals)
