  • Creep failure analysis of bars sustaining constant tensile loads
    Germain, Yves ; Molinari, A.
    Life time and failure modes are predicted for metallic bars sustaining tensile creep. Experimental results show that a ductile or a 'brittle' mode of fracture occurs depending respectively on whether ... the nominal applied stress is large or small. The analysis is based on a modeling of void nucleation and growth in which damage evolution is controlled by two mechanisms of plastic flow in the matrix material. Fracture is supposed to occur when the porosity attains a critical value which depends on the mode of fracture considered. Experimental results are explained and described in terms of the proposed model.
