Study on the Stability of Thin-walled Cylindrical Shell Structure with Large Rectangular Openings under External Pressure
In this paper,though taking thin-walled cylindrical shell with large rectangular openings as the object of research,the buckling analysis of the structure was carried out by using ANSYS Workbench soft-ware,including the relationship between critical instability load and buckling behavior and the various geo-metric influencing factors and material parameters.The results show that,the shell's diameter to thickness ratio mainly influence the structure's critical instability load.When the modulus of elasticity keeps con-stant,the relationship between the critical instability load and the yield strength of the material tends to the linearity.The variation in the diameter to thickness ratio and material parameters doesn't change the struc-ture's buckling behavior and tendency.
