Abstract

The problem of second and third approximation is solved by studying the flexure of a pre-twisted solid of elliptical cross-section already faced and solved by R. Giovannozzi [1] for the solution of first approximation. The authors report the final stress and strain expression to the already mentioned approximation and some diagrams and visioning the respective progress.
