Fatigue crack growth of cast austenitic stainless steels

工程科学学报, 2015
The influences of stress ratio, single overload and high-low loading sequence on the fatigue crack growth of Z3CN20-09M cast austenitic stainless steels were studied with compact tension specimens. When the stress intensity factor range is identical, the

Experimental investigation of fatigue crack initiation from notch for 2024 T351 Al-alloy

Fracture and Structural Integrity, 2020
In this investigation, fatigue criterion was established to predict crack-initiation at the tip of a notch in aged hardening aluminum alloy. This criterion was used to predict the residual lifetime in aeronautical structures using concept of local stress

Damage and Deterioration Characteristics of Sandstone Under Multi-Stage Equal-Amplitude Intermittent Cyclic Loading and Unloading

Buildings
The surrounding rocks of roadways are typically subjected to cyclic loading–unloading stress states in underground engineering. In addition, cyclic loads are discontinuous under real working conditions, usually while loading rock mass in a cycle ...

MODELLING OF STRESS GRADIENT EFFECT ON FATIGUE LIFE USING WEIBULL BASED DISTRIBUTION FUNCTION [PDF]

, 2013
In the present paper, a new approach is developed in order to take into account the stress gradient effect on fatigue life of structural components. The proposed approach is based on the weakest link concept in which the shape coefficient of the Weibull ...
