15 صفحه اولA Fatigue Life Prediction Method Based on Strain Intensity Factor
In this paper, a strain-intensity-factor-based method is proposed to calculate the fatigue crack growth under the fully reversed loading condition. A theoretical analysis is conducted in detail to demonstrate that the strain intensity factor is likely to be a better driving parameter correlated with the fatigue crack growth rate than the stress intensity factor (SIF), especially for some metall...
متن کاملEffect of material uncertainties on fatigue life calculations of aircraft fuselages: a cohesive element model
The present paper deals with the effect of uncertainties on the prediction of fatigue failure of aerospace and mechanical components. Typically the design of such structures has been based on costly experiments or modified versions of Paris law which are applicable to very restricted range of conditions. The present formulation employs cohesive zone elements in order to resolve the fractured zo...
متن کاملSonic Fatigue Study of an Aircraft Flap like Structure
Acoustic fatigue failures in aircraft are caused by the dynamic response of structures to unsteady pressure loading from aerodynamic and engine acoustic sources. Structural life is difficult to assess accurately and maybe affected by steady, thermal, in-plane and out-of-plane panel loads. These failures result in increased maintenance and inspection burdens associated with the operation of the ...
متن کاملStudy of fatigue and workload among aircraft de-icing technicians
BACKGROUND: Fatigue and workload experienced by aircraft de-icing personnel have been largely neglected in occupational health and safety research. OBJECTIVE: To provide an initial assessment of fatigue and workload among de-icing ground crews. METHODS: Company records were used to reveal possible relationships between different variables (age, seniority, truck type, and work shift). A group of...
