Abstract
Description of the results of an experimental program undertaken to determine strain distributions around holes, strain concentrations, failure initiation and failure mechanisms. The effects on these basic variables of material (glass-, boron-, graphite-epoxy), ply orientation, and stacking sequence are discussed. The approach used was to measure deformations and strains to failure on the surface and on the edge of the cutout using a combination of strain gage, photoelastic coating, and moire techniques and to compare some experimental results with analytical predictions.
