Statistical consideration of fatigue damage accumulation

Mechanics of Materials, 1992
Abstract Statistical analysis has been conducted to model the damage accumulation processes during stress- and strain-controlled fatigue tests. The energy criterion has been adopted to discuss the fatigue crack initiation condition. It has been found that such fundamental and yet quite empirical equations to describe the well-known Coffin—Manson and ...

Fatigue damage accumulation around notches

Materials Testing, 2004
Abstract Notched compact tension specimens of type 304 stainless steel (notch tip radius of 1 mm and 4 mm) were low-cycle-fatigued at stress ratio R = −1 and 0.05 in order to investigate the through-thickness fatigue damage accumulation around the notch.

Fatigue damage accumulation in Ni3Al and NiAl

Materials Science and Engineering: A, 1995
Abstract The accumulation of fatigue damage during strain-controlled cycling (low-cycle fatigue) of single crystals of NiAl and very coarse-grained polycrystals of Ni3Al + W in air at room temperature is described. Surface topography was studied for all test materials by scanning electron microscopy and, in the case of Ni3Al + W polycrystals, also by

Microscopic Analysis of Fatigue Damage Accumulation in TiAl Intermetallics

Volume 7A: Structures and Dynamics, 2014
In order to design efficient and light components for the aircraft industry preserving the safety of the design, more sophisticated design criteria are required for the application of new materials. In particular, the usage of novel manufacturing processes to produce advanced materials such as the gamma titanium aluminide alloys (γ-TiAl) requires the ...

Fatigue damage accumulation in pultruded glass/polyester rods

Composites, 1989
Abstract Stress controlled fatigue tests have been carried out on pultruded 60 vol% E-glass polyester rods. Damage evolution throughout life was monitored using stiffness decay and replication techniques. During the first 10–20% of life a rapid decay in stiffness was related to individual fibre fracture, debonding, and matrix cracking (which was also

A study on fatigue damage accumulation based on continuum damage mechanics

2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012
On the basis of the continuum damage mechanics, a new low cycle fatigue damage accumulation model, which takes the coupling effect of damage and strain into account, is proposed. The model has some practical values because of its clear physical meanings.

Fatigue damage accumulation in grey cast iron

International Journal of Fatigue, 1987
Abstract Observations and results of constant-amplitude, completely reversed strain-control fatigue tests are reported for a pearlitic grey cast iron. Both axial and torsional cyclic load cases have been investigated. A damage parameter based upon the product of the tensile stresses and strains ( σ max Δe /2) gives good correlation of all the ...

Fatigue and accumulation of damage in reinforced plastics

Composites, 1977
A wealth of experimental data on fatigue of reinforced plastics is currently available to designers. Much of this relates to unidirectionally-reinforced materials, but there is also a great deal of information on the behaviour of laminates of varying degrees of complexity.

Experimental investigation of fatigue damage accumulation

Aircraft Engineering and Aerospace Technology, 1972
IN 1945, M. A. Miner presented his approach for cumulative damage in metal fatigue to the American Society of Mechanical Engineers. In this approach, the expended life of a specimen is defined to be equal to the summation of the number of cycles that are applied at each different stress level when expressed as a percentage of the number of cycles that ...

Fatigue damage accumulation: Aspects of environmental interaction

Materials Science, 2006
The corrosion fatigue lifetime of materials can be predicted by simulating the multi-stage damage process with regard for the action of both corrosion and mechanical factors. This action can be represented in the form of damage accumulation maps, where the processes of pitting, pit-crack transition, and cracking are identified.
