Abstract In this paper the problem of cumulative fatigue damage is considered. On the basis of the invariable succession postulate and the invariable damage postulate, a general form for a one-damage-parameter cumulative-damage model is developed. It has been shown that some of the models previously proposed can be obtained as a particular case of ...

Clinical Orthopaedics and Related Research, 1977
Flexural fatigue tests of bovine bone specimens produced fracture surfaces that were transverse on the tension side and oblique on the compression side. Similar fracture patterns were produced by bending tests with a single applied loading. Microscopic examination of flexural fatigue specimens prior to complete established that fatigue fracture is ...

Basal slip dominant fatigue damage behavior in a cast Mg-8Gd-3Y-Zr alloy
International Journal of Fatigue, 2019Low fatigue strength has been a major barrier for structural applications of cast magnesium alloys. It is important to understand the fatigue mechanisms and improve the fatigue lives of these alloys. Stress-controlled high-cycle fatigue behaviors of cast

Relationships between the characterization and the nondestructive detection of fatigue damage are discussed and illustrated. Inspection methods presently used at overhaul facilities are reviewed, and examples of the equipment used and the results obtained are given. The advantages and limitations of currently used nondestructive methods are summarized.

Fatigue damage effect approach by artificial neural network
International Journal of Fatigue, 2019This study is concerned with the fatigue strength behaviour of chassis components made of steel S420MC. Experimental results show differences when applying sequences of loads, but also when the effect of the operating temperature is taken into account ...

The plane frame version of a steel jacket platform is analysed by mode acceleration method. The local stresses in the joints of an offshore structure subjected to random wave/current load are derived from the nominal stress response of the structural members using the stress concentration factors.

Fatigue damage investigation of ultra-large tire components
International Journal of Fatigue, 2019Off-road ultra-large tires experience different modes of heat-related fatigue failure in operation due to inherent material defects that grow into visible cracks under service loads.

Evolution of fatigue damage using the fatigue damage map method
Theoretical and Applied Fracture Mechanics, 2006Using only readily available material properties and the concept of the fatigue damage map the work attends to develop a methodology able to predict crack tip propagation rates characterising each of the fatigue stages, namely crack arrest, microstructurally and physically short crack (Stage I), long crack growth (Stage II) and Stage III growth.

Analysis of the effects of vibration modes on fatigue damage in high-speed train bogie frames
Engineering Failure Analysis, 2018High-speed trains have been rapidly developing in China, and their operating speeds have reached 350 km/h. In order to ensure the structural reliability and safety of high-speed trains, dynamic design methods need to be adopted to extend the fatigue life
