摘要：

A non-linear theory of thin-walled elastic beams of open cross section is formulated in terms of a space curve endowed with several director fields, one for each of the plates composing the beam. Physically meaningful constraints among the directors are introduced and a technique for the algebraic elimination of the corresponding Lagrange multipliers from the field equations is discussed. Compatibility conditions for a minimal set of strain measures are presented. © 1979 Springer-Verlag.
