Abstract

If we cut the circular annulus of Figure 8.1 along two radial lines, \(\theta \!=\!\alpha ,\beta \), we generate a curved beam. The analysis of such beams follows that of Chapter 8, except for a few important differences — notably that (i) the ends of the beam constitute two new boundaries on which boundary conditions (usually weak boundary conditions) are to be applied and (ii) it is no longer necessary to enforce continuity of displacements (see §9.3.1), since a suitable principal value of \(\theta \) can be defined which is both continuous and single-valued.

Notes

  1. 1.

    In particular, (10.11, 10.12) can both be satisfied by setting \(D\!=\!0\) and (10.2010.23) reduce to only two independent equations if \(D\!=\!0\).

  2. 2.

    except that \(4D'\) replaces 2D.
