Method for reducing the computation resources required for determining damage in structural health management system

摘要

A method for determining damage in a structural health monitoring system comprising a plurality of sensors distributed across a structure is disclosed. The method includes decomposing the plurality of sensors into a plurality of sub-arrays. Each sub-array is associated with a current sensor. For each sub-array, data is collected, the data corresponding to electrical signals produced by waves initiated by the current sensor and detected by a receiving sensor. The data is used to calculate a damage measurement for the sub-array. Then, the damage measurement determined for each sub-array is combined to determining an overall damage assessment from the combined damage measurements.
