The proposal aims to apply the approach of the two parameter constrained based fracture mechanics on determination of the fatigue threshold value of stress intensity factor. The different levels of a stress constraint due to the specimen geometry will be quantified by means of the T-stress. The main goal of the project is to elucidate the effect of the parameter T on threshold value of propagation fatigue cracks. The problem will be solved numerically by means of the finite element method and results will be compared with experimental measurements provided mainly on steels of the Czech production (for example steel 12050.1) The results obtained contribute to those achieved during solution of the basic project and makes it possible better estimations of fatigue life time of real structures. |
