  • Mechanical testing of powders and powder compacts
  • 1983
  • Ingår i: Scandinavian journal of metallurgy. - 0371-0459 .- 1600-0692. ; 12:6, s. 302-311

    • Results from standard triaxial, uniaxial and bending tests are presented. Triaxial tests were performed at pressures in the range 0-200 MPa. Both initial loose powder samples and cylindrical precompacted specimens were studied under hydrostatic conditions. Most of the total volume compaction occurred at pressures below 10 MPa. Triaxial tests with superimposed axial loads showed no softening despite a 30% shortening of the length of specimens which initially were 60 mm long. Specimens deformed in triaxial tests showed a higher density and a higher uniaxial compressive strength than specimens compacted under hydrostatic conditions.

  • Microstructures and mechanical characteristics of the Tännäs augen gneiss, Swedish Caledonides
  • 1980
  • Ingår i: Geologiska föreningens i Stockholm förhandlingar. - : Informa UK Limited. - 0016-786X. ; 102:4, s. 319-334
  • Tidskriftsartikel (refereegranskat)abstract
    • The mechanical behaviour, microstructure and substructure of the classic Tannas augen gneiss of the Swedish Caledonides are presented. Progressive deformation of granodiorite to augen gneiss and mylonite is shown to take place in an isochemical environment with redistribution of megacrysts to surrounding matrix. Experimental deformation of natural rocks from the Tannas Augen Gneiss Nappe has been carried out in the temperature range of 20-600oC and under confining pressure of 100-700MPa. The highest strength found is for the fine-grained mylonite. The augen of the gneiss show brittle behaviour under all test conditions, and temperature has a limited effect on the ultimate strength of the matrix of the augen gneiss. Microstructures have been analysed by means of optical microscopy and transmission electron microscopy. The progressive deformation is brought about by dislocation glide and dislocation creep. Subgrain formation, recrystallization and straining of new grains are observed at all stages of the progressive deformation of the matrix while the augen behavior is brittle

  • The influence of microcrack density on the elastic and fracture mechanical properties of Stripa granite
  • 1985
  • Ingår i: Physics of the Earth and Planetary Interiors. - 0031-9201 .- 1872-7395. ; 40:3, s. 161-179
  • Tidskriftsartikel (refereegranskat)abstract
    • Presents results from a great number of mechanical tests on Stripa granite containing various amounts of microcracks. Variations in the microcrack density were obtained by shock-heating the rock at different temperatures in the range 100-600°C for 3 h. The results presented are obtained from sound velocity measurements, uniaxial compression tests, Brazilian tests and three-point bending tests. The density of microcracks in the heated rock is studied by means of optical microscopy, SEM and differential strain analysis

  • Education in mining and rock excavation in Sweden
  • 1984
  • Ingår i: The 12th Congress of World Mining Congress, New Delhi, November 19-23, 1984. - Calcutta : American Institute of Chemical Engineers.
  • Konferensbidrag (refereegranskat)abstract
    • Education in Mining and Rock Excavation in Sweden can be subdivided into higher education, upper secondary school education and in-service training. Higher education is provided at the University of Lulea and leads to a Masters degree and to a Licentiate or Doctor of Engineering degree in mining. The higher education curriculum was replanned in connection with the move to Lulea in 1972 from the Royal Institute of Technology in Stockholm to involve higher specialization and to cover both the mining and the underground construction sectors. The upper secondary school education is given at the College of Mining and Metallurgy in Filipstad and leads to a secondary-school engineering degree. In-service training courses are given for working professionals by the Division of Advanced Vocational Training in Lulea and by equipment suppliers. Vocational training is pursued at some upper secondary schools in cooperation with the mining companies.
