The purpose of this two-part article is to theoretically establish and experimentally support a simple method for calculating shear band angles and shear band widths in tension or compression samples commonly used to investigate mechanical properties. The method is illustrated in conjunction with experimental results on the yielding behavior and shear band formation in tension and compression of an ultra fine grained Fe-10% Cu alloy, properly milled and consolidated. The experimental techniques for preparing the samples, their microstructural characteristics and the details of the performed mechanical tests will be reported elsewhere, but a brief summary is contained in Part 2 of the present article. In Part 2 comparisons are made between theoretical predictions for pressure-sensitive plastic materials established in Part 1 and experiments on the yield behavior of an ultra fine grained Fe-10% Cu alloy along with observations on shear band orientations and widths.
