Key components of large structures in aeronautics industry are required to be made light and have long enough fatigue lives. It is of vital importance to estimate the fatigue life of these structures accurately. Since the FCG process is affected by various factors, no universal model exists due to the complexity of the mechanisms.

ABSTRACT In order to investigate the dynamic shear characteristics of rubber sand under cyclic loading, a series of cyclic torsional shear tests was conducted using a hollow cylinder torsional shear apparatus. The effects of four cyclic vertical stress ratios (CVSRs = 0.15, 0.25, 0.35, and 0.45) and four cyclic ...

Cyclic fatigue crack growth in silicon nitride: Influences of stress ratio and crack closure
Acta Metallurgica et Materialia, 1995Abstract The characteristics of cyclic fatigue crack growth was investigated in silicon nitride which hardly shows rising R-curve behavior, using single edge precraked beam specimens. Crack growth behavior is known to be explicable by a power law relationship including both the stress intensity range ΔK and the maximum stress intensity Kmax; i.e.

The characteristics of cyclic fatigue crack growth in a silicon nitride which hardly shows rising R-curve behavior were investigated by using specimens having an indentation-induced flaw. V-shaped behavior was observed in the relation between the maximum stress intensity factor K[sub max] and crack growth rate.

Abstract In a previous study, the hypothesis that dislocation arrangements do not change while Masing behavior occurs in materials was proposed. However, by validating the hypothesis via TEM observation, the authors incidentally found that dislocation structures are not always the same during Masing behavior.

AN APROACH FOR CYCLIC STRESS RATIO OF LIQUEFIED OR UNLIQUEFIED SOILS
2006Bu çalışmada, yinelemeli (tekrarlı) yüklerin belirlenmesi için kullanılan deprem ile zemin parametrelerine, zeminin kayma dalga hızları (Vs) ve deprem dalgasının hakim periyodu da (T) eklenerek alternatif bir analitik ilişki geliştirilmiş ve kayma gerilme oranı (KGO) olarak isimlendirilmiştir.

The influence of stress ratio of cyclic loading on properties and mechanism of nitinol fracture
Physicochemical Mechanics of MaterialsThe shape memory alloy (nitinol) was studied under low-cycle fatigue at a frequency of 0.5 Hz, different levels of maximum stresses σmax and stress ratio R (0.1 and 0.5) in the loading cycle. It was shown that regardless of the level of σmax, the energy dissipated during deformation of nitinol at R = 0.1 always exceeded that inherent to it at R = 0.5 ...
