TAILIEUCHUNG - A combined numerical and statistical analysis for prediction of critical buckling load of the cylindrical shell with rectangular cutout

In this paper, buckling behavior of aluminum cylindrical shell with rectangular cutout, subjected to axial pressure was studied by means of finite element simulations. The effects of geometric parameters (R, t, a, b and L) on the first buckling mode capacity of the shell were studied. | A combined numerical and statistical analysis for prediction of critical buckling load of the cylindrical shell with rectangular cutout Engineering Solid Mechanics 7 2019 35-46 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm A combined numerical and statistical analysis for prediction of critical buckling load of the cylindrical shell with rectangular cutout Omid Sam Daliria b Mohammadreza Farahania and Majid Farhanga a School of Mechanical Engineering College of Engineering University of Tehran Tehran Iran b Institute of Smart Systems Technologies Alpen-Adria-Universität Klagenfurt Klagenfurt Austria A R T I C L EI N F O ABSTRACT Article history Detecting how a cutout affects the critical buckling load in circular cylindrical shell is a serious Received 10 October 2018 issue for the design of the shells used in marine structures aerospace and automobile applications.

The effects of geometric 10 December 2018 Keywords parameters R t a b and L on the first buckling mode capacity of the shell were studied. The Circular cylindrical shell effects of these factors and their interaction effects were investigated by combined numerical and Critical buckling load statistical analysis. The results show that R b t and Rt b were the main effective factors of critical Cutout buckling load. Based on the statistical analysis a model for prediction of the critical buckling load Finite element simulation was obtained with an accuracy equal to 95 R2 R2 pred and R2 adj . This equation could be Statistical analysis used to predict the critical buckling load of an isotropic circular shell with a rectangular cutout. 2019 Growing Science Ltd. All rights reserved. 1.
