Abstract
Two models, clamped, initially deflected, elliptical and rectangular panels are used as bases to study the behavior of delaminating composite panels. Both models appear to be capable of serving the desired purpose. The elliptical model is compared qualitatively to test results generated for a [90/0/ + 45] delamination in a [90/0/ ± 45]3s graphite/epoxy coupon tested in compression. The orientation, shape, and deflection correlation were very good. The short transverse stress field correlated qualitatively with the observed delamination growth. The observed self-similar growth shape was also obtained by the analytic model.
