During this quantity a survey of the main appropriate nonlinear crack versions is supplied, with the aim of interpreting the nonlinear mechanical results taking place on the tip of macrocracks in quasi-brittle fabrics - reminiscent of concrete, rocks, ceramics, polymers, high-strength metal alloys - and in brittle-matrix fibre-reinforced composites.

Moreover the main focus lies on the interactions of the di- and trivalent cations Al3+, Cu2+, Mg2+, Zn2+ with the mica structure.

G. , 1995). 2 show, the intercalation of the bi- and trivalent cations is no simple ion exchange mechanism of the interlayer potassium versus the new cations. However, no strong decrease of the 5 – MINERALOGICAL CHARACTERIZATION 41 potassium amount is detectable during the treatment. Thus it can be assumed, that the K+ as well as the Al3+-, Mg2+-, Cu2+-, or Zn2+-ions appear together in the interlayer region, which is one of the main reasons for its expansion. 2 Chemical data of the treated muscovites.
