Abstract

surface structures of the vehicle suffer thermal loadings during the high speed flight. The thermal stress distribution of typical titanium alloy plate under thermal loadings is studied based on the assumption of uncoupled thermal-structural properties and nonlinear von Karman large-deflection strain-displacement relationship; the critical buckling temperature of simply supported titanium alloy plate is obtained through generalized eigenvalue analysis, and the change of the response characteristic before and after plate buckling is obtained by further analysis. The results show that, simply supported titanium alloy plate in uniform temperature field is prone to buckling because of the relatively low critical buckling temperature. The modal and frequency of the plate were changed before and after the buckling, structure shows more characteristics of higher order modes.
