Experimentally, it has been observed for single crystals of a number of metals that the critical resolved shear stress, τcrss, is a function of the dislocation density, rhod, as where τ0 and a are constants. for some metal, the critical resolved shear stress is 2.33 mpa at a dislocation density of 2.64 × 104 mm-2. if it is known that the value of a for this metal is 2.46 × 10-3 mpa-mm, compute the τcrss (in mpa) at a dislocation density of 1.08 x 106 mm-2.
