114 Study on Safety Structures for Human Friendly Robots : On the Wall Buckling and the Collapse of Skin Rectangular Tubes due to Lateral Loads
Details
The final goal of this study is to produce safety structures for human friendly robots. This paper describes an experimental and FEA investigation on the wall buckling and the collapse of a skin rectangular tube due to lateral loads. A moire topography system is proposed in order to observe the web and the flange synchronously and in whole. The experimental and FEA results show that slight initial flaws as well as initial deflection of the walls affect sensitively the behaviors and the maximum load of the skin structure.
