Supported by: DFG Research Center MATHEON, project C8
Description:
The work for this research project has been continued in several
directions. The paper [1] concerning the
 
optimization of rods
and shells has been accepted after revision. In [2], a new
 reduction approximation
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 [4].
A new type of asymptotic analysis  for
merely Lipschitzian curved rods 
has been developed in the papers [5], [6], 
[7].
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
monograph [3].
