de Jong, S. (author)The predesign document of DEFMEF presents the decisive requirements for the DEFMEF language and the associated DEFMEF translator. It also shows a basic technical design, which fulfills the requirements. DEFMEF as a software design language has been designed so, that it is possible to describe both a technical design and a detailed design with it...report 1991

Dekker, G.J. (author), de Jong, H. (author), Moek, G. (author)Under contract to ESA, NLR has developed a flexible simulation package, named PROMISE, and a set of simulation models of the ESA proposed NAVSAT satellite-based navigation system. These were completed in 1984. In a continuation contract, described in this report, a number of extensions have been developed and implemented, and a number of...report 1987

Nederveen, A. (author), de Jong, J.B. (author)The influence of the approximation of the lower end of the load spectrum was investigated by comparative tests using the Basic F-27 test programme and an extended version, containing three times more cycles per flight. Crack growth was studied on notched sheet specimens made of Alclad 202U-T3 and Alclad TOT5-T6. Fatigue life tests were done on...report 1981

de Jong, G.J. (author)The concept of Introduction of biaxial loads in a specimen made of sheet material using soft clamps of unidirectional aramld composite sheet is presented. Using this concept it Is possible to generate realistic biaxial tensile stress states in specimens made of sheet materials without the introduction of unwanted fatigue critical areas.report 1990

de Jong, J.B. (author), Schütz, D. (author), Lowak, H. (author), Schijve, J. (author)A description is given of the development of a standardized load sec[uence which may be considered to be representative for the load history of the wing root of transport aircraift. It is proposed to adopt this standardized sequence for various aeronautical fatigue testing purposes. The standardization proposal was jointly developed by...report 1973

de Jong, J.B. (author), van Lummel, C.W.J. (author)A method is developed to quantify the severity of recorded stress spectra in terms of potential crack growth. The CSI (Crack Severity Index) defined is Intended for application to the stress monitoring results obtained in RNLAF F-16 aircraft. However, the methodology can be used for other applications, associated with other types of stress spectra.report 1986

Prins, J.J.M. (author), Dieleman, P. (author), de Jong, H. (author)The Hermes manipulation system (HERA) is a sophisticated space manipulator system, which has to perform tasks ranging from berthing to tool operation in various operational modes from fully automatic to purely manual. The HERA system main contractor is Fokker Space & Systems B.V. (FSS). Development and qualification of such a space-based...report 1989
