Effect of elevated temperature on critical load in stability tests of the steel plate

Abstract

This paper presents the results of a study on the effect of epoxypolyester based powder coatings on the critical strength of plate specimens made of rolled steel sheets. The results show that the model using planar elements gives more accurate results than the model using three-dimensional elements. The best agreement with experiment was obtained with Ansys results using Eigenvalue bucling, less than 1%. The lowest experimental agreement was with the results obtained in Ansys using solid elements, about 70%.
