摘要：
Residual stresses exist in composite structures free from external forces or constrains and generally are very undesirable because can contribute to damage or failure. in this paper a moire interferometric hole drilling procedure is applied for residual strain measurements in graphite/PEEK composite laminates. Experimental results obtained are reported and a numerical calibration procedure is proposed for residual stress evaluation from the experimental data.
