Abstract
A method for determining optimal locations of a plurality of sensors for damage detection in a structural health monitoring system includes providing a one or more signal performance characteristics, spatial parameters describing a layout of a structure, and generating a layout for the plurality of sensors according to the signal performance characteristics and the spatial parameters. An estimated largest critical damage size that may not be detected by sensors arranged according to the first layout is determined. The layout is edited so as to reduce the estimated largest critical damage size to be less than or equal to a selected maximum size requirement.

A method for determining optimal locations of a plurality of sensors for damage detection in a structural health monitoring system, comprising:
- providing one or more signal performance characteristics of the plurality of sensors;
- providing spatial parameters describing a layout of a structure;
- generating a layout for the plurality of sensors on the structure according to an estimated spacing between the plurality of sensors, the estimated spacing based on the signal performance characteristics and the spatial parameters;
- determining an estimated largest critical damage size on the structure that may not be detected by sensors arranged according to the first layout;
- and
- editing the layout on the basis of the estimated largest critical damage size so as to reduce the estimated largest critical damage size to be less than or equal to a selected maximum size requirement.
