The work for this research project has been continued in several
directions. The paper  concerning the
optimization of rods
and shells has been accepted after revision. In , a new
technique has been developed to overcome the
well-known ``locking phenomenon'' in the numerical approximation of
thin curved rods. In this context, we also refer to .
A new type of asymptotic analysis for
merely Lipschitzian curved rods
has been developed in the papers , ,
A considerable part of the results established in this field by
J. Sprekels and D. Tiba within the past years will be contained in the
