STOCHASTIC-DETERMINISTIC PARAMETER ESTIMATION FOR FRACTURE MODELLING OF FIBER REINFORCED CONCRETE

In this work we are trying to substitute pullout tests with three-point bending tests. In order to achieve that, a relation between the two tests (pullout and three-point bending) has to be established. It is assumed that this relation is deterministic and so a combination of stochastic - deterministic model is a result. Stability and accuracy of the stochastic-deterministic inverse model is going to be assessed through additional experiments that are under way.
