Effects of Defects – Embedded Materials
GKN Aerospace forms Titanium Honeycomb panels at elevated temperature. In order to prevent the contamination of the Titanium, the parts are covered with stainless steel foil. The high temperature and high contact pressure may cause steel particles to be embedded in the titanium face sheet. GKN Aerospace needs an analytical method to predict the effect of those inclusions of dissimilar materials in the fatigue life of its products.
