On the stresses and deflections calculus in bending the cylindrical naturally twisted bars, with constant pitch

Résumé

The present paper deals with some aspects of the stresses and deflections calculus in case of the cylindrical, naturally twisted bars, with constant pitch, on the basis of assumptions on the linear-elastic behavior of the material and on the small bending deflections. In the first section of the paper, the main aspects concerning the geometry generation and classification of the naturally twisted bars are taken into account. Furthermore, the generalized formulas for the above-mentioned calculus are presented. Also, some aspects of the generalized formulas used are provided. In last section of the paper, on the basis of the generalized formulas, a case study and conclusions are presented.
