The bifurcation of a toroidal shell segment with initial imperfection which are subjected to
lateral or hydrostatic pressure is studied under the assumption that the initial imperfection …

This paper is concerned with the post‐buckling behavior of an inextensible, linear elastic,
cylindrical hinges‐ended strut with rectangular cross‐section, under axial compression. Let …

This paper revisits the effect of secondary bifurcations on the post-buckling response of a
simple 3D system of elastically restrained beams, first discussed by Luongo in [19]. Our main …

In this paper we discuss the numerical calculation of secondary buckling of structures. This
kind of stability problem contains two parameters (one is conservative load parameter, the …

The post-buckling behavior of a compressed, simply supported, shearable elastic rod on a
nonlinear elastic foundation is studied. For the critical values of auxiliary parameter the …

The general theory of elastic stability invented by Koiter, 1945 [311] motivated the
development of a series of asymptotic approaches to deal with initial postbuckling behavior …

In some structures subjected to compressive loads, there are many different buckling modes
for the same buckling load, or artificially imposed approach or equality of buckling loads with …
