Fatigue Life Prediction of Microstructures
Volume 8: Mechanics of Solids, Structures and Fluids, 2012The formation and early growth of fatigue cracks in the high cycle fatigue regime is influenced by microstructuctural features such as grain size and morphological and crystallographic texture. However, most fatigue models do not predict the influence of the microstructure on early stages of crack formation, or they employ parameters that should be ...

Abstract In the design of composite structures for durability and damage tolerance, the primary concerns are out-of-plane failures, such as delamination, material degradation associated with environment, stability under compression loading, large degree of scatter in fatigue life, and bearing failure of joints.

Weld residual stresses have a great effect on the fatigue strength of welding structures. As an internal stress, the residual stress is unfounded to be treated as the conventional mechanical load during the fatigue safety assessment due to its relaxation

Prediction of Tensile Fatigue Life for Unidirectional CFRP
Journal of Composite Materials, 2000Tensile fatigue strength in unidirectional CFRP depends on time and temperature as well as number of cycles. A prediction method of fatigue strength proposed [14] for polymer composites meeting certain conditions and confirmed for flexural fatigue strength of satin-woven CFRP laminates is applied to the tensile fatigue life of unidirectional CFRP.

Fatigue Life Prediction Models
2011Chapter 4 deals with low cycle fatigue tests and derivation of fatigue life prediction models curve-fitted to the fatigue test data for Sn–Ag–Cu and Sn–Cu solder alloys. The fatigue tests were conducted under low cycle fatigue test conditions over a wide range of isothermal temperatures (−40°C to +125°C) and frequencies.

Thermal fatigue life prediction
Materials Testing, 2004Abstract For clarifying the behavior of thermal fatigue and verifying the role of Coffin-Manson’s law in thermal fatigue, out-of phase type thermal fatigue tests were carried out on ferritic ductile cast iron. As a result of the tests, the dependence of thermal fatigue life and the plastic strain produced in each cycle on cyclic peak ...

Model for life prediction of fatigue–creep interaction
Microelectronics Reliability, 2008This paper discusses the development of a procedure for computing creep and stress relaxation at the critical location in a through-hole structure. A high-speed methodology was developed for calculating cyclic creep and stress relaxation at critical locations of a pile on elastic foundation subjected to cyclic thermomechanical loading.

Prediction of Acoustic Fatigue Life
1961Current procedures used by the airframe industry for predicting fatigue life of structures loaded by high-energy acoustical noise are reviewed. Deficiences in the methods are discussed and future work is suggested. The need for spectrum-type fatigue tests is emphasized.

Fatigue of Composites—Fatigue Modulus Concept and Life Prediction
Journal of Composite Materials, 1986Fatigue behavior of glass fiber reinforced epoxy composite materials has been studied analytically. A new concept called "fatigue modulus," which is defined as a slope of applied stress and resultant strain at a specific cycle is introduced. Fatigue modulus degradation is studied using an assumption that the fatigue modulus degrada tion rate follows a ...
