STABILITY AND LOAD-CARRYING CAPACITY OF RIBBED SHELLS WITH IMPERFECTIONS OF FORM

摘要

A finite difference method is used to analyse critical loads of cylindrical shells with initial imperfections of different types, both regular and local. Ribbed shells are analyzed with allowance, for discreteness in the arrangement of the ribs. Dependencies of dimensionless critical loads on dimensionlcss amplitudes of imperfections are calculated. Features of the behavior of the curves describing these dependencies are discussed.
