A Note on Axioms of Structural Health Monitoring

Abstract

In this paper, the axioms of Structural Health Monitoring (SHM) presented by Worden et al. [2007] are discussed in detail. In many cases, the intent of the axioms is found to be correct, but the terminologies used are confusing. Also, it was found that some axioms could be derived from other axioms that were given in the paper. Based on the discussion presented in this paper, it is suggested to replace the seven axioms given by Worden et al. [2007] with a set of three new axioms. Counter-examples are presented to dispute the axioms where necessary. Similar to Worden et al. [2007], the term axiom is used outside its meaning in the field of mathematics and logic. In both the papers, the term axiom refers to the fundamental truths, which cannot be contradicted in the field of SHM.
