Abstract

We proposed an inverse method, using a simply supported circular plate under lateral concentrated load, for the simultaneous determination of two elastic constants E and u from strain data of two-element strain-gage rectangular rosette. Several series and different position of strain-gauges provided full field information about strain field of the plate. An overdeterministic approach using least-square method is implemented to fit the experimentally determined strain field to the theoretical solution. Accuracy of the proposed method is verified experimentally.
