Stability analysis of steel compression members under shock loads [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2018 This paper presents the results of a numerical analysis of the elastic-plastic behaviour of steel compression members subjected to compression with a permanent pre-deformation in the longitudinal axis by a longitudinal indispensable shock load.

A non-linear analysis of the longitudinal static stability of light, multi-engined aircraft
, 1979 The longitudinal handling qualities of light aircraft have traditionally been assessed in terms of the slope of the static stability trim curves. This method of assessment is simple in terms of analysis as well as being a relatively easy task for the pilot to perform. The theory is however based on a simple linearised model of . the aircraft'and omits,

Analysis and Recovery of Aircraft Deep-Stall Phenomena Using Bifurcation Analysis
IEEE Access, 2020 In this paper, the problem of deep-stall recovery will be studied for the aircraft without longitudinal static stability. A new longitudinal short-period deep-stall model is established in the presence of time-varying distributed delays.
