摘要：

The uniaxial behavior of aluminum polycrystals is simulated using a rate-independent incremental self-consistent elastic-plastic polycrystal deformation model, and the results are evaluated by neutron diffraction measurements. The elastic strains deduced from the model show good agreement with the experimental results for the 111 and 220 reflections, whereas the predicted elastic strain level for the 200 reflection is, in general, approximately 10 pct too low in the plastic regime.
