Information × Registration Number 0206U002454, 0103U005063 , R & D reports Title Theoretical foundations, mathematical basis and experimental provision of fatigue life prediction of aircraft structures popup.stage_title Head Petro Fomichov, Registration Date 09-02-2006 Organization National Aerospace University named by N.E.Zhukovsky "Kharkov aviation institute" popup.description2 Cyclic deformation and fatigue characterristics of 30ХГСА, 40Х, 45 steels and Д16Т aluminium alloy have been explored at different modes of loading. The fatigue life computation method under the condition of complex loaded state has been developed and compared with experimental data. The local loading cyclogram computation method in the concentrator of tension under the condition of the airplane wing panels composite loading in fligth and during loading time has been recommended. Rational relationship of geometrical parametrs for stringers endings which provide the airplane wing panels fatigue life have been established. The fatigue life computation method for construction elements at the bigarmonical airplane wing loadigg has been developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
