Abstract: A general damage parameter for fatigue and creep-fatigue applications based on the hypothesis that damage is dependent on the internal total octahedral strain energy is derived. This general ...

Abstract: Because of the complex nature of the fatigue process, it is only recently that reasonably effective analysis procedures for predicting finite-fatigue life for simple notched coupons have evolved. ...

Abstract: This is the second in series of two papers generated from a recent study on risk-based analysis for developing strategies to ensure pipeline integrity. This paper (Part II—Applications) focuses ...

Abstract: As pipelines age, a flaw population that varies initially along the pipeline can advance in size and number. Analysis of the serviceability of pipelines based on either inline inspection or ...

Abstract: An explanation for the observed difference between the values of the long-life, fatigue-notch strength-reduction factor (Kf ) and the elastic stress concentration factor based on the influence ...

Abstract: This paper uses examples to illustrate problems in damage analysis under nonproportional cycling. Nonproportional histories examined include multiaxial loading with either fixed or rotating principal ...
