Report on Workshop 5

  • S. Mindess
Part of the Nato Conference Series book series (NATOCS, volume 4)


Dr. Shah began by summarizing the conclusions of the preceding workshop on fragmentation. There was produced a list of those subject areas in which more knowledge was needed before the efficiency of fragmentation could really be improved:
  1. 1.

    Methods of breaking

  2. 2.

    Modes of deformation and fracture

  3. 3.

    Stress analysis

  4. 4.

    Critical materials properties (Kic, γ eff. and the static, dynamic, acoustic, thermal etc. characteristics)

  5. 5.

    Energy balance in demolition and fragmentation

  6. 6.

    Improvement to the various techniques

The questions that had been raised were:
  1. 1.

    Is fracture machanics a useful tool for the fragmentation of concrete? Do we know enough about fracture mechanics to influence demolition and fragmentation?

  2. 2.

    What else do we need to know?

  3. 3.

    Are other approaches, such as continuous damage theory, helpful?
