Abstract
AbstractFor an orthotropic torsion bar with L‐shaped or cruciform cross‐section, the studied torsion problem can be reduced to a boundary value problem of elliptic partial differential equation. The studied region is separated into several rectangular sub‐regions, and the series solution is suggested to solve the problem for the individual sub‐region. By using the continuation condition for the functions on the neighbouring sub‐regions, the investigated solution is obtainable. Finally, numerical results for the torsion rigidities of bars are given to demonstrate the influence of the degree of orthotropy. Copyright © 2001 John Wiley & Sons, Ltd.
