Buckling Analysis of an Arbitrary Shell by Curved Triangular Elements.

Abstract

The report is concerned with application of the curved triangular finite elements in the buckling analysis of an arbitrary shell. The linear membrane displacements and quintic transverse displacements are assumed and these displacement fields are coupled through the surface curvature transformation and the local-global base coordinate transformation. An iterative eigenvalue solution scheme is used to determine critical loads. As examples doubly curved shells are analyzed and their results presented. As a special case the computer program can be reduced to handle buckling of plates. (Author)
