Available in PDF, EPUB and Kindle. Book excerpt: A combined analytical and experimental program was conducted in order to develop a semi-empirical sonic fatigue design method for curved and flat graphite-epoxy skin-stringer panels. A range of multi-bay panels was subjected to high intensity noise environments in a progressive-wave tube. Shaker tests were also performed in order to provide additional random fatigue data. Finite- element analyses were carried out on the test panel designs, generating static strains and frequencies. Multiple stepwise regression analysis was used to develop the sonic fatigue design method. Design equations and a nomograph are presented. Comparisons of sonic fatigue resistance between graphite and aluminum panels were also carried out. The design method developed is presented as a self-contained section in this report and is suitable for practical design use.

Available in PDF, EPUB and Kindle. Book excerpt: The papers contained herein were presented at the First International Conference on Composite Structures held at Paisley College of Technology, Paisley, Scotland, in September 1981. This conference was organised and sponsored by Paisley College of Technology in association with The Institution of Mechanical Engineers and The National Engineering Laboratory (UK). There can be little doubt that, within engineering circles, the use of composite materials has revolutionised traditional design concepts. The ability to tailor-make a material to suit prevailing environmental conditions whilst maintaining adequate reinforcement to withstand applied loading is unquestionably an attractive proposition. Significant weight savings can also be achieved by virtue of the high strength-to-weight and stiffness-to-weight characteristics of, for example, fibrous forms of composite materials. Such savings are clearly of paramount importance in transportation engineering and in particular aircraft and aerospace applications. Along with this considerable structural potential the engineer must accept an increased complexity of analysis. All too often in the past this has dissuaded the designer from considering composite materials as a viable, or indeed better, alternative to traditional engineering materials. Inherent prejudices within the engineering profession have also contributed, in no small way, to a certain wariness in appreciating the merits of composites. However, the potential benefits of composite materials are inescapable. The last two decades have seen a phenomenal increase in the use of composites in virtually every area of engineering, from the high technology v vi Preface aerospace application to the less demanding structural cladding situation.

Available in PDF, EPUB and Kindle. Book excerpt: The papers contained herein were presented at the Third International Conference on Composite Structures (ICCS/3) held at Paisley College of Technology, Paisley, Scotland, in September 1985. The Conference was organised and sponsored by Paisley College of Technology. It was co sponsored by the Scottish Development Agency, the National Engineering Laboratory, the USAF European Office of Aerospace Research and Development, and the US Army Research, Development and Standard isation Group-UK. It forms a natural and ongoing progression from the highly successful First and Second International Conferences on Composite Structures (ICCS/l and ICCS/2) held at Paisley in 1981 and 1983, respectively. To label composites as rather specialised, sophisticated, space-age structural materials would be to underestimate greatly their wider industrial potential. It is unquestionably true that they will play an increasingly dominant, if not decisive, role in aerospace engineering. Indeed a future aircraft industry without composites as the prime structural materials is inconceivable. However, in an energy-conscious world the high specific weights and stiffnesses of composites make them an attractive proposition in every sphere of transportation engineering. This fact is soundly underlined in one of the Plenary papers contained herein and in one of the sessions devoted to this subject. I t would also be a considerable mistake to interpret composites as simply lightweight alternatives to conventional metallic structural materials.
