van Leeuwen, H.P. (author), Groep, F.F. (author), Schra, L. (author), Dam, N. (author)Test results reported in the literature show that in creep cracking tests at elevated temperature under steady load, the crack growth rate correlates best with the contour integral C*, also called J*, in comparison to other possible parameters. In the case of fatigue at elevated temperature, the crack growth rate correlates best with C* if...report 1987

Groothuizen, R.J.P. (author), van den Berg, J.I. (author), van Leeuwen, W. (author)Design of robots is an iterative process. Therefore software tools for analysis of different concepts without the need to build hardware models are required. The software tool ROBDYN can be used for analysis of the dynamics properties of a robot. Main constituents are a dynamics algorithm and a facility for the preand postprocessing of data. The...report 1986

van Leeuwen, H.P. (author)The concept of fugacity is explained. Application of compressibility and fugacity data in hydrogen embrittlement calculations is discussed. Equations of state are reviewed. Compressibility factors and fugacity coefficients are calculated. A best estimate is proposed.report 1983

van Leeuwen, H.P. (author)The literature concerning the application of fracture mechanics to the growth of creep cracks is discussed. As an introduction it is shown that linear elastic fracture mechanics have been applied successfully to the residual strength of brittle materials crack growth due to stress corrosion and crack growth due to fatigue. Next the methods are...report 1983

ten Have, A.A. (author), Nederveen, A. (author), de Jonge, J.B. (author), van Leeuwen, H.P. (author)This memorandum presents results of crack propagation tests on notched Alclad 2024-T351 sheet specimens. Two thicknesses were investigated (2 mm and 8 mm), as well as various spectrum modifications and the effect of clustering of severe flights within the test load sequence.report 1982

(author)Circumferentially notched round specimens of 4340 type steel have been plated in a galvanic bath known to be embrittling. The specimens were reclaimed by stripping and baking. Half the specimens were replated in a non-embrittling bath. Reclamation did not remove all traces of hydrogen embrittlement, but raised the threshold stress to such a...report 1979
