Stability of structured sheet metals during buckling

From the journal Materials Testing

Abstract

Structured materials can be a progressive alternative to commonly used flat sheets. There is an enormous range of possibilities for using structured sheet metals due to their better stability. However, the effective use of these materials as well as their implementation in production requires precise knowledge about specific properties of structured sheet metals. The aim of this work is to obtain new knowledge about stiffness and stability during the deformation of this material. The structured sheet metals were investigated by means of buckling tests. The steel type investigated is a commonly used deep-drawing steel DC04. Six types of structure arrangements were compared to non-structured (flat) specimens as a reference. The influence of the type of structure arrangement as well as the deformation speed on the mechanical properties was investigated.

M. Sc. Evgenia Ermilova, born in 1990, studied metal forming at Peter the Great St. Petersburg Polytechnic University, Russia. In 2014 she defended her Master of Science degree in Engineering under a double Master's degree program between the Peter the Great St. Petersburg Polytechnic University, Russia and the Brandenburg University of Technology in Cottbus-Senftenberg, Germany with a specialization in metallurgy and materials technology. Her graduation thesis topic was “Estimation of a Stability of Structured Sheet metals in Buckling”. At present she is a PhD student at the Brandenburg University of Technology of Cottbus-Senftenberg in Germany.

Dr.-Ing. Fedor Kazak, born in 1975, studied Physical Metallurgy and Thermal Treatment of Metals at Volgograd State Technical University, Russia. He finished his Dr.-Ing. in the field of Materials Science and Engineering at the Brandenburg Technical University in Cottbus-Senftenberg in 2015. His professional experience includes the analytical and mechanical characterizations of metal-based materials. Currently he is an Executive Employee in Quality Assurance/Working Process at HWL Löttechnik GmbH, Berlin, Germany.

Prof. Dr.-Ing. Sabine Weiß, born in 1964, received her Dipl.-Ing. in Physical Metallurgy and Materials Science from the Technical University (RWTH) in Aachen, Germany in 1990. She completed her Dr.-Ing. in Materials Science and Engineering at the same university in 1997. As Head of the fatigue group in the Institute of Product Engineering, Chair for Materials Science at the University Duisburg-Essen she completed her Priv.-Doz. in Materials Science and Engineering in 2007. Her research was in the fields of texture analysis, grain growth, fatigue and microstructure analysis. At present she is Professor for Materials Science at the Brandenburg Technical University in Cottbus-Senftenberg, Germany and Head of the Chair of Physical Metallurgy and Materials Science. Her area of research lies within the fields of fatigue, erosion wear, mechanical behavior of structured sheet metals and the corrosion of technical metallic materials.
