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 ... 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 …
Witryna8 wrz 1999 · It is found that the bonded structure is sensitive to imperfections if 0.575 < r < 1. Some asymptotic results valid in the thin–layer limit are derived and comparisons are made with the classical model for plates on elastic foundations.
