Plastic deformation of b.c.c. polycrystals

Plastic deformation of b.c.c. polycrystals is investigated on the basis of a single-crystal deformation model. Many of the calculations previously only presented for f.c.c. polycrystals are given here for the b.c.c. structure. In particular, stress-strain curves in tension and simple shear are presented along with the b.c.c. limit yield surface and the polycrystalline Bauschinger effect. The model employed is one suggested by Budiansky and Wu (1902) and Kröner (1961). Many of the results correspond to those which would be obtained from Taylor's model, or Lin's extension to the Taylor model.
