Second and Third Approximation in the Flexure Study of a Pre-Twisted Bar of Elliptical Cross-Section

  • A. Fichera
  • E. Guglielmino
  • R. Sinatra


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.
