Influence of Observation Errors on the Identification of External Loads


Article Preview

This paper will report on the investigation results of the influence of observation errors on the identification of external loads in case of the bending problem of a beam. It is found that the resultant force and the resultant moment of the loads will be conserved despite of the divergence of the identified load distribution, when the observation errors are within a certain tolerance. This fact is applicable to the problem of identifying a small defect.
