... Abstract A graphite-epoxy tapered-box structure, which consisted of two honeycomb skin panels fastened to a spanwise spar with intermediate chordwise ribs, fractured during testing. Hinge-line deflection of the front spar was revealed. Through-thickness cracks in the forward and trailing edges...

... for quality assurance of composite structures. Of the many different NDE techniques, ultrasonic inspection continues to be the leading nondestructive method for inspecting composite materials, because measurements can be quantitative and the typical defect geometries and orientations lend themselves...

... that were about 2.6 mm thickness were butt joint in treated condition using filler wire of similar composition by gas tungsten arc welding to form single nozzle assembly. No post-weld heat treatment was employed. In general, defect-free, high-quality welds can be obtained by GTAW in this steel. However...

.... It was then realized that cleavage fracture in crystalline materials could not be based simply on a normal stress criterion (e.g., see Honeycombe ( Ref 2 ). Many new tools and techniques for studying fracture surfaces have become available and made possible a more complete understanding of fracture processes...
