On a theory of the quantification of the lack of knowledge (LOK) in structural computation

Abstract : Still today, some of the phenomena which occur in structural dynamics cannot be described, even using a properly updated model: some uncertainties remain. This paper presents the basic concepts of a new theory which uses the concept of Lack of Knowledge (LOK) to model the uncertainty using two bounds of the energy in each substructure. The inverse problem, which consists in determining the Lack of Knowledge for each substructure from test results on the whole structure, has been studied on a simple example.
