WitrynaIn Abaqus/Standard the Riks method ( Unstable collapse and postbuckling analysis) can be used to solve postbuckling problems, both with stable and unstable postbuckling behavior. However, the exact postbuckling problem often cannot be analyzed directly … Witryna1 cze 2024 · This article covers the imperfection sensitivity and design of tori-spherical domes under external pressure. In the second section of this article a numerical model and experimental results of a tori-sphere are presented. The third section presents different numerical design concept for tori-spherical shells.

The numerical analysis of the role of imperfections on the stability of wrinkling is presented in §5. … WitrynaIn many cases a series of closely spaced eigenvalues indicates that the structure is imperfection sensitive. An eigenvalue buckling analysis will not give accurate predictions of the buckling load for imperfection-sensitive structures; the static Riks procedure should be used instead (see “ Unstable collapse and postbuckling analysis ...
