Wanhill, R.J.H. (author), Schra, L. (author), 't Hart, W.G.J. (author)This report compares the mechanical properties, fracture toughness and fatigue crack growth properties of the damage tolerant/medium strength aluminium plate alloys 2024-T351, 2324-T39, 8090-T651 and 8090-T8171. The main objective, in view of previous work, was to determine whether damage tolerant 8090-T8171 plate can advantageously replace the...report 1995

Moss, A.C. (author), 't Hart, W.G.J. (author)This investigation examined carbon/epoxy and aramide/epoxy composites in interlaminar shear and in open-hole tensile tests at 90 to the unidirectional fibre orientation. Epoxy resin was also tested under tension. Photomicroscopy and the S.E.M. were used to study the fracture surfaces. Wet tests were performed to investigate the influence of...report 1986

't Hart, W.G.J. (author), Nederveen, A. (author)Constant amplitude and flight simulation fatigue tests have been carried out on sulphuric acid, chromic acid and phosphoric acid anodized specimens. A comparison was made with the fatigue behaviour of bare sheet material. Before fatigue testing the fracture strain of the anodic layers was determined.report 1980
