Originální abstrakt
This article presents the research of effect of model imperfections on the local buckling of compressed stiffeners in finite element (FE) analyses. Improved FE models with imperfections provide more accurate simulations of thin-walled semi-monocoque structures, where natural curvatures of structures are insufficient. Main outcomes of these analyses are designs of practical types of imperfections with appropriate ratio values and demonstration of trends from graphic comparisons of results.
