    Notes: [Auszug] In contrast to the polymer scientist, who has the privilege of calling upon an ever-expanding array of compositions from which to choose, the ceramic scientist has had to devote years of intensive research to the refinement of a relatively limited number of systems. So it is exciting news to hear ...

    THE THRESHOLD STRESS INTENSITY RANGE IN FATIGUE (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Fatigue & fracture of engineering materials & structures 1 (1979), S. 0 
    Details
    ISSN: 1460-2695

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract— The parameters are considered that control the threshold stress intensity in fatigue and relationships existing between these parameters are examined. A new relation is derived which is shown to be consistent with experimental data for a 0·15%C, 1·5%Mn steel.

    THE EFFECT OF CATHODIC PROTECTION POTENTIAL ON CORROSION FATIGUE CRACK GROWTH RATE OF AN OFFSHORE STRUCTURAL STEEL (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Fatigue & fracture of engineering materials & structures 19 (1996), S. 0 
    Details
    ISSN: 1460-2695
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract— Duplicate tests have been performed to determine the effect of cathodic protection potential on corrosion fatigue crack growth rate of a modern offshore structural steel, produced by thermo-mechanically controlled processes. The experiments were carried out using compact tension specimens exposed to artificial seawater at 10°C and subjected to constant amplitude loading at 0.35 Hz. Reproducible results showed that the merits of cathodic protection potentials are strongly dependent on stress intensity ratio R and stress intensity range ΔK. It appears that a specific value of cathodic potential may not give comprehensive protection against corrosion fatigue within the spectrum of variable amplitude loading experienced in service. Fractography showed the initiation of secondary cracks on the fracture surface to be associated with the dissolution of calcium sulphide inclusions, regardless of imposed cathodic potential.

    Microstructure development and dielectric properties of fast-fired BaTiO3 ceramics (1986)
    Springer
    Journal of materials science 21 (1986), S. 3575-3580 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The technique of zone sintering was applied to three BaTiO3 source materials; studies were made in air, oxygen and vacuum. The optimum firing conditions suggested for the zone sintering of these materials were a temperature of 1450° C and a time in the hot zone of 5 min. The temperature dependence of the dielectric constant could be closely related to the firing conditions and material microstructure. Lower room-temperature dielectric constants and lower Curie temperatures were found as the holding time in the hot zone was increased, yielding larger grained structures.

    Effective dynamic response of paired Gill anemometers (1977)
    Springer
    Boundary layer meteorology 11 (1977), S. 33-37 
    Details
    ISSN: 1573-1472
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract It is shown that the instrument transfer functions for the longitudinal and transverse components of wind measured by paired Gill anemometers are for practical purposes the same as for individual anemometers even when the mean wind direction is at some angle to the anemometers. However, the effective response time is a function of the relative wind direction, and appropriate values are given.

    The Koorin nocturnal low-level jet (1985)
    Springer
    Boundary layer meteorology 32 (1985), S. 133-154 
    Details
    ISSN: 1573-1472
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract It has been long known by Australian meteorologists that a nocturnal jet is a frequent feature of the low-level wind profile at Daly Waters in the Northern Territory of Australia. The Koorin Expedition during the southern winter of 1974 obtained data on wind and temperature profiles in the boundary layer which form an ideal base for the study of this phenomenon. In this paper, a simple model of the jet is described and the results of the model are compared with observations. The model is essentially a development of the pioneering work of Blackadar, who proposed that a low-level jet could develop as an inertial oscillation. The observations do show some of the features of the model.
