MATHEMATICAL MODELS OF THE IMPROVEMENTED CALCULATION ON DURABILITY OF CONTINUOUS AVIATION CONNECTIONS WITH ACCOUNT OF THEIR COMPLIANCE
Abstract
Mathematical models and algorithms for the calculation, which allows to improvethe strain-stress state of continuous aviation connections and joints with variation in wall thick- ness are constructed.The boundary-value problem by definition of a stress state of a bound- aryplane strain ("boundary layer" type) for rigid fixed edges of a cylindrical shell and an annu- lar plate at axisymmetric loading is formulated and solved. Calculations of stresses in flange connection are carried out. Graphs of these stresses on a thickness of a plate and a shell are constructed.The boundary-value problem by "boundary layer" definition is modified for the account of connected elements of structures compliance is modified and the estimation of its influence is given
