Buckling of beams and plates onto an intermediate support studied by the dynamic relaxation method

Abstract

Problems involving beams or plates which deflect until contact is made with internal restraints are examined using a modified form of the dynamic relaxation method. Three particular problems are considered in detail. The first a concerned with a laterally loaded beam restrained by an internal point support. Next the effect of a restraint surface positioned parallel to and a short distance away from an axially loaded strut is considered. Finally a study is made of the postbuckling of a square plate onto a line support positioned parallel to the loaded edges.
