| Abstract |
Problems of the identification of mechanical characteristics of materials on
the basis of test data for structures made of these materials have drawn rather much
attention [1-16]. These problems are in essence inverse problems which can be
ill-conditioned and need regularization methods to be solved. This approach is
particularly attractive for determining mechanical characteristics of composite
materials like tapes and braids, since it permits one to overcome technical
difficulties of identifying these characteristics in the direction orthogonal
to the reinforcement direction. In addition, this approach indirectly takes
into account technological features manufacturing the structures.
In the present study, an approach is suggested which makes it possible to
obtain good agreement between computational and experimental data by extending
the problem of identification. It is shown on the basis of an example of the
processing of the results of a realistic experiment that this approach gives
the discrepancies between computational and experimental parameters which are
several times smaller than those for the traditional approach. |
