Problem 8.33 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, asτ (cross) = τ(0) + a(rhod)^1/2where τ0 and a are constants. for some metal, the critical resolved shear stress is 4.9 mpa at a dislocation density of 1.8 x 104 mm-2. if it is known that the value of a for this metal is 2.5 x 10-4 mpa-mm, compute the τcrss (in mpa) at a dislocation density of 2.9 x 107 mm-2.
