INVERSE STOCHASTIC MODELS FOR FIBER REINFORCED CONCRETE

In a material model each constituent should be adequately described, especially the interface between the matrix and fibers that is determined with the 'bond-slip' law. 'Bond-slip' law describes relation between the force in a fiber and its displacement. However, bond-slip model is deterministic and cannot explain variations in experimental results. In order to accommodate experimental results we have adopted stochastic model that is based on the 'fiber bundle representation'.
