Wanhill, R.J.H. (author)Flight simulation fatigue crack propagation tests with gust spectrum loading were carried out on 2024-T3/carbon-epoxy, 7475-T76l/carbon-epoxy and Ti-6Al-4V/carbon-epoxy laminates with nominal weight savings of -30% as compared to equivalent 2024-T3 panels. The performance of the 2024-T3/carbon-epoxy laminates was much superior to those of the...report 1978

Wiggenraad, J.F.M. (author)The influence of bending-torsional coupling on the buckling load of general orthotropic, midplane symmetric and elastic plates has been studied. First this effect has been analysed for the case of infinitely long plate strips, resulting in approximate analytical solutions, which can be presented graphically for the entire range of the elastic...report 1977

Wiggenraad, J.F.M. (author)A finite element model has been developed, which incorporates the bending-torsional coupling effect, as it occurs in general orthotropic, midplane symmetric, elastic plates in order to analyse its influence on the buckling behaviour of such plates. Some results have been compared with known exact and approximate solutions.report 1977
