"The proposed project deals with numerical tools for description of interaction of fibres and composite matrix. The interaction is studied in composite analyses as well as in reinforced concrete analyses. The interaction is modelled by Lagrange multipliers and the formulation is solved within framework of the FETI (Finite Element Tearing and Interconnecting) method. The numerical framework is in the centre of attention, and the derivation of bonding/debonding laws is not studied. The perfect interaction, the linear debonding law and the general debonding law are adopted from literature and they are used in the proposed framework. The FETI method is slightly modified in order to solve the problems with slip between constituents. The proposed numerical tools can be parallelized readily and large numerical analyses may be solved."@en .
