Prediction of Mechanical Properties of Thin-Walled Bar with Open Cross-Section under Restrained Torsion

Thin-walled bars with an open cross-section are widely used in mechanical structures where weight and size control particularly required. Thus, this paper attempts to propose a theoretical model for predicting the properties of thin-walled bar under restrained torsion. Firstly, predictions shear stress, buckling normal secondary stress condition torsion was developed based on theory. Then, physical test finite element modeling data were employed validate predictions. The results indicate that show good agreements experiments. Therefore, proposed could be prediction response annular section
