An experimental and analytical evaluation of the compressive response of two composite, notched stiffened panels representative of primary composite wing structure is presented. A three-dimensional full-field image correlation technique is used to measure all three displacement components over global and local areas of the test panels. Point-wise and full-field results obtained using the image correlation technique are presented and compared to experimental results and analytical results

Results of a simple calibration test of this image correlation technique are also presented. * Aerospace Engineer, Structural Mechanics Branch. Senior Member, AIAA.
