Evaluation of Edge Cracks in Cross-Ply Laminates Using Image Correlation and Thermoelastic Stress Analysis

Abstract:

Article Preview

The paper describes initial work on using 2D digital image correlation (DIC) and thermoelastic stress analysis (TSA) to obtain data from edge cracks in cross-ply laminates. It is demonstrated that detailed data related to the crack tip stresses can be obtained using TSA. The work reveals some of the limitations experienced when using DIC in applications where high spatial resolution is required. A detailed discussion is provided along with an outline for future work.
