Title: Crack Identification in Structures Using Optimal Experimental Design

This paper investigates the problem of identifying the location, size and orientation of cracks in structures using an array of strain measurements. It presents statistical identification methods and computational tools that are required to identify cracks from strain measurements. It also addresses the experimental design problem related to finding the optimal location, orientation, number and density of sensors for reliable crack detection, along with the computational difficulties involved. The effectiveness of the proposed methodologies is illustrated using simulated data from a single crack in a plate subjected to static loading
