Generating Methods of Severe Load Spectra for Airplanes Based on Statistic Analysis in Flight Subjects

open access: yesHangkong gongcheng jinzhan, 2019
Nowadays, the mean load spectra is mostly used in fatigue test for aircraft, but it has the defects of long fatigue cycle. The severe load spectra is used instead, which can shorten the test time greatly. In order to meet the demand of full-scale fatigue

Probabilistic fatigue life prediction of metallic components based on continuum damage mechanics

open access: yesXibei Gongye Daxue Xuebao, 2021
Based on continuum damage mechanics, a probabilistic method of predicting high-cycle fatigue life for metallic components is proposed. First, macro-meso two-scale stress-strain equations are established by combining Eshelby-Kroner localization law and ...
