New Ways of Representing Finite Element Results of Shell Structures

The Finite Element Method is used in many computer programs to analyse the mechanical behaviour of shell structures. Although this method provides good quantitative insight into the mechanical behaviour of shell structures, it provides little qualitative insight. This master graduation thesis is aimed at expanding Finite Element Analysis (FEA)...

Buckling Behavior of Spirally Welded Steel Tubes

This report deals with the buckling behavior of spirally welded steel tubes. First, an existing analytical solution and the results of an extended experimental investigation are investigated. The imperfections measured during testing are investigated and classified, and methods are proposed to incorporate them into finite element models....
