Design for fluctuating stresses
WebFigure (3–6) Some stress-time relations: (a) fluctuating stress with high- frequency ripple; (b and c) non-sinusoidal fluctuating stress; (d) sinusoidal fluctuating stress; (e) repeated stress; (f ) completely reversed sinusoidal stress.Figure (3–6) illustrates some of the various stress-time traces that occur. The components of stress, some of which are … WebMar 8, 2024 · So, study of fluctuating stresses came needed to make design safer. Since, c yclic stress variations were irregular and non-analytic, various models came in suggestion for the study. AT LAST, Sine curve came to be taken as the easiest and popular model. This model was based on Stress -Time relationship.
