DAMASCOS damage location demonstrator for structural health monitoring

The problem of damage detection and identification has a natural hierarchical structure. At the higher levels, one might require the diagnostic to return say, information about the expected time to failure of a structure, while at the lowest level, the question is simply of whether a fault is present or not. In many ways, the latter is the most fundamental. In response to the need for robust low-level damage detection strategies, the discipline of novelty detection has recently evolved. The problem is simply to identify from measured data if a machine or structure has deviated from normal condition, i.e., if the data are novel. The method requires a bank of normal condition data against which the possible damage condition data are compared.
