Twenty papers will aid investigators conducting failure analysisof advanced composite and metallic materials. Composites papersfocus on failure of continuous fiber graphite/epoxy materialsystems, covering delamination propagation, the effects of impactand radiation damage, and the fracture surface characterization ofnotched laminates. Several papers on fractography of ferrous alloyscover steam turbine blading steels, pressure vessel weldments,fatigue damage in carburized steel, and ductile-brittle transitionin austenitic stainless steels.
