Mean Stress Effect - an overview ScienceDirect Topics
WebTest data tends to fall between the Goodman and Gerber lines. For hard steels, the ultimate strength approaches the true fracture stress, therefore Goodman and Morrow equations will produce similar results. For ductile … The general trend given by the Goodman relation is one of decreasing fatigue life with increasing mean stress for a given level of alternating stress. The relation can be plotted to determine the safe cyclic loading of a part; if the coordinate given by the mean stress and the alternating stress lies under the curve … See more Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an … See more The relations can be represented mathematically as: See more • Fatpack.
