Paper Abstract

For many structural applications it is highly desirable to be able to measure two or more axes of strain at a single point. In many cases one dimensional strain measurements may be insufficient to fully characterize events or lead to erroneous predictions. This paper will provide an overview of the use of multi-axis fiber grating strain sensors to perform structural diagnostics. Examples of usage of multi-axis fiber grating strain sensors in a smart bearing cell for damage assessment of bridges and for adhesive joints associated with aircraft will be given as illustrations of these methods.
