Identification of a Defect Using the Equivalent Load Method


Article Preview

This paper will propose an identification algorithm for a small defect in the case of the bending problem of a beam. That is to say, the part where a defect exists is replaced by an equivalent load term. It shows that the defect can be accurately identified even there is observation error if the problem of identifying a defect is converted to that of identifying a load.
