EXPERIMENTAL INVESTIGATION OF THE BUCKLING OF PLATES WITH RESIDUAL STRESSES

LOCAL BUCKLING TESTS OF PLATE ELEMENTS IN SQUARE COLUMNS BUILD-UP BY WELDING ARE SUMMARIZED. THE EXPERIMENTS WERE CONDUCTED TO VERIFY THEORIES FOR THE ELASTIC AND ELASTIC- PLASTIC BUCKLING OF PLATES WITH EMPHASIS ON THE EFFECT OF RESIDUAL STRESS. ASTM A7 AND A514 STEELS WERE USED. THE SQUARE SECTION SIMULATED PLATES SIMPLY SUPPORTED AT THE UNLOADED EDGES, AND THE LENGTH OF THE COLUMN WAS CHOSEN SO THAT END CONDITIONS HAD NO EFFECT EITHER ON THE RESIDUAL STRESS DISTRIBUTION OR ON THE LOCAL BUCKLING STRENGTH OF THE COLUMNS. EXPERIMENTAL RESULTS SHOWED GOOD CORRELATION WITH THEORETICAL PREDICTIONS INCLUDING THE EFFECT OF RESIDUAL STRESS FOR ELASTIC BUCKLING AND FOR ELASTIC-PLASTIC BUCKLING BASED ON THE TOTAL STRAIN THEORY. THE RESULTS INDICATE THAT CONSIDERABLE POSTBUCKLING STRENGTH MAY BE EXPECTED FOR ELASTIC BUCKLING OF PLATES, ALTHOUGH NOT FOR ELASTIC-PLASTIC BUCKLING.
