    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 1 (1987), S. 0 
    Details
    ISSN: 1747-6593
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Following Publication of early proposals for the Reservoirs Act 1975, a systematic programme of reservoir investigation and repair work was carried out by the Department of the Environment for Northern Ireland, Water Service.The paper describes the full procedure followed for data collection, inspections, risk classification and stability and hydraulic investigations of 60 ‘large raised reservoirs’ impounded by dams up to 42 m high and up to 148 years old. Also described are examples of some unusual repair works carried out, and the implementation of a recording, monitoring, and inspection system which now continually oversees all of the reservoirs involved.

    Notes: [Auszug] The carbon fibre reinforced silica system has many interesting properties from this point of view. There is a large difference in the Young's moduli of fibre (E 50 x 106 pounds/inch2) and matrix (E 10 x 106 pounds/inch2), so that for continuously reinforced composites the greater part of the load ...

    Fracture mechanism of brass/Sn-Pb-Sb solder joints and the effect of production variables on the joint strength (1986)
    Springer
    Journal of materials science 21 (1986), S. 1730-1734 
    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 effect of various processing parameters on the strength of brass/Sn-Pb-Sb solder joints containing 0–10% Sb have been determined and the fracture mechanism examined by microscopical techniques. Soldering times up to 1 h at 300° C caused the greatest decrease in the strength of joints with solder containing 3% Sb. After 1 h joints with solders containing 0, 3, 5 and 10% Sb all had a similar strength. Cooling rates after soldering (from water quenching to furnace cooling) and joint gap thickness (from 0.05 to 0.20mm) had a negligible effect on joint strength. Fracture occurs through a region of high porosity in the solder at the brass/ solder interface. The presence of Sb and/or cuboids of SnSb in the solder increases the number and size of the pores and the cuboids tend to physically locate the pores at the interface.

    Measurement of the fracture toughness of polycrystalline diamond using the double-torsion test (1994)
    Springer
    Journal of materials science 29 (1994), S. 4750-4756 
    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 double-torsion test was employed to study the processes of crack propagation and to measure the fracture toughness of polycrystalline diamond. The value of fracture toughness of about 13 MPa m1/2 is surprisingly high. Inhomogeneity in microstructure may cause discontinuous crack propagation which makes it difficult to study the subcritical crack growth behaviour of this polycrystalline material. Subcritical crack growth is shown to be negligible and crack deflection is shown to be an important toughening mechanism in polycrystalline diamond.

    A strong carbon-coated silica fibre (1967)
    Springer
    Journal of materials science 2 (1967), S. 206-210 
    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 Freshly drawn silica fibre was coated with carbon by passing the still-hot filament through a chamber containing heated acetylene. As the coating thickness was increased, by increasing the temperature of the fibre or acetylene, the tensile strength of the fibre first increased and then decreased. This decrease in strength was concluded to be caused by reaction between the coating and the silica fibre. Optimum conditions were found which gave fibres with a mean strength of 500 000 lb/in.2 (1 lb/in.2= 7x10−2 kg/ cm2).
