A micro-macro model derived from slip theory is shown. It is applied to the modeling of nickel base single crystal superalloys. The experimental data include monotonic and cyclic solicitations at 950°C. The general agreement between tests and numerical simulations is good for all the studied orientations: 〈001〉, 〈011〉, 〈111〉, and 〈123〉. The model is simple enough to be implemented in a finite element code as shown in a future part of the paper.
