QUALITY DESCRIPTION OF FOLDING PHENOMENON OF THIN-WALLED CYLINDRICAL RODS MADE OF STEEL R 35 DURING LOSS OF STABILITY IN PLASTIC STATES

Krzysztof Murawski

 

ABSTRACT



A description of the folding phenomenon of thin-walled cylindrical axially compressed rods during loss of stability in plastic states is presented in the paper. The course of quasi-static load and rod deformation thanks to simultaneous camera filming with the divided screen method is analysed. Changes of crystal grains in a polished cross-section before and after the experiment made on a R35 steel rod (PN-73/H-72240) are presented.

Key words: stability, plastic state, thin-walled, rod..
