Full Field Strain Analysis of Aircraft Sandwich Structures

Record type: Conference or Workshop Item (Paper)

A study of the application of two full field optical strain analysis techniques to aircraft standard carbon fibre
composites is carried out. The goal of the work is to assess the feasibility of using the techniques on full scale
tests of secondary sandwich structure aircraft panels. The work concentrates on two techniques: Digital Image
Correlation (DIC) and Thermoelastic Stress Analysis (TSA). The DIC work focuses on the accuracy of the strain
measured using different correlation patterns and parameters and the TSA concentrates on the interpretation of
the data from different surface ply configurations. The work shows that it is possible to obtain meaningful data
from the two techniques and acts as the preliminary confirmation exercise prior to full scale testing.
