News & Infos Fatal shear failure
In tunnelling, the consequences of shear failure of soils can be devastating.
News & Infos Tracing potential collapse
Progressive loss of strength along potential shear planes or shear bands has to be covered by the analysis model.

Adaptive Fixed Crack Model
Developed by Weihe and Ohmenhäuse, the Adaptive Fixed Crack model features:

  • mode I (tension failure) and mode II (shear failure)
  • realistic modelling of shear bands
  • realistic shape of settlement trough cracking under tension
  • reduced computation time thanks to efficient and robust implementation (consistent elastoplastic tangent matrix).
