An elastic-plastic single-crystal behaviour based on a micromechanical description is formulated in large strains. Self-consistent model leads to macroscopic behaviour. This one is coupled with Rice criterion to predict the apparition of instabilities. FLD are plotted for monotonic or complex loadings. The results agree with experimental observations.
