Abstract

The inverse finite element method is used for shape , strain and stress measurement in various plate and shell structures. The health monitoring of structures has been investigated using the results of inverse finite elements in this research. A new iMITC4 four-node inverse quadrilateral finite element shell element has been developed based on the first-order shear deformation theory of the shells and its application has been investigated for shape and strain measurement as well as structural health monitoring for finding crack location in stiffened plates. The iMITC4 element has a very good and accurate capability for use in monitoring the health of structures. In addition, the mentioned element has good and reliable performance despite the strain data containing noise.
