Numerical round robin on micromechanical models

Continuing former activities on ''Local Approaches'', ESIS TC8 started a numerical round robin on the application of ''Micromechanical Models'' for describing fracture phenomena in ferritic steels, both ductile tearing and cleavage. The paper reports the results of Phase I, i.e. the numerical analyses of a standard smooth and a notched tensile specimen to identify critical damage parameters for ductile tearing at room temperature and for cleavage at -196 degrees C, respectively. The round robin will continue with numerical simulations of fracture mechanics tests.
