Title: Buckling And Post Buckling Of Structural Components
Author: Deshpande, Shruti
Abstract: Structural members and components, such as shells and trusses of different geometries, form the intricate and deep seated parts in the manufacturing of missiles submarines, rockets, airplanes, automobiles etc and find applications in civil structures such as bridges. These members are comprised of components like conical frusta, cylindrical panels and shallow trusses. In many cases, the sole purpose of such shell structures is to absorb the energy generated due to impact which means, that these structures are subjected to heavy loads and can experience failure due to buckling. The objective of this work is to study the buckling and post buckling behavior of such members. The study is carried out using finite element analysis. The widely implemented softwares ANSYS APDL and ANSYS Workbench are used to perform the analysis. The components analyzed consist of shell structures such as conical frusta and cylindrical panels, and other structures like the shallow truss, diagonal truss and the shallow arch. These structures are analyzed for their buckling and post buckling behavior when subject to specific loading conditions and geometric, contact and material non-linearity. The results compare favorably with known solutions.
