Abstract
A deterministic non-destructive evaluation system for composite damage assessment and repair includes structure of interest, non-destructive evaluation data and strength test data obtained on the structure of interest, finite element analysis performed on a structural model modified by the non-destructive data and the strength test data, a strength-to-indication correlation based on the finite element analysis and deterministic non-destructive evaluation predictions and recommendations based on the strength-to-indication correlation.
