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

van Leeuwen, H.P. (author), de Rijk, P. (author), Boogers, J.A.M. (author), Huisman, H.N. (author), Wanhill, R.J.H. (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

van Leeuwen, H.P. (author), Schra, L. (author)The literature is reviewed with respect to: - tests conducted to investigate crack re-initiation under dynamic load and arrest of a running crack - metallurgical sources of rate effects - available data for aerospace engineering materials - mechanical sources of rate effects, i.e. dynamic crack tip stresses and kinetic energy effects Conclusions...report 1975

García, Á. (author), Schlangen, E. (author), Van de Ven, M. (author), Van Vliet, D. (author)The objective of this research is to examine the induction heating of mastic through the addition of electrically conductive fillers and fibers (graphite and steel wool), and to prove that this material can be healed with induction energy. The effect of fibers content, sand–bitumen ratio and the combination of fillers and fibers on the induction...journal article

García, A. (author), Schlangen, E. (author), Van de Ven, M. (author), Van Vliet, D. (author)It is well known that the healing rates of asphalt courses increase with the temperature. A new method, induction heating, is used in this paper to increase the lifetime of asphalt concrete pavements. Mastic will be first made electrically conductive by the addition of conductive fibers. Then it will be heated via induction energy. This will...journal article
