A mild steel specimen subjected to Brinell hardness test, if the indenter diameterand surface area of indentation are 19 mm & 39 mm2respectively. Determine theindentation diameter, D1 obtained after the test. Also, determine the forcedapplied on the mild steel specimen in N, if Brinell hardness value is 1629
From the work of D. C. Jillson, Trans. AIME 188, 1129 (1950), the following data were taken relating to the deformation of zinc single crystals. The crystals have a normal cross-sectional area of 122 x 10-6 m2. ϕ = angle between loading axis and normal to slip plane λ = angle between loading axis and slip direction F = force acting on crystal when yielding begins a. Identify the slip system for this material. b. Calculate the resolved shear τRSS and normal σn stresses acting onthe slip plane when yielding begins. c. From your calculations, does τRSS or σn control yielding? d. Plot the Schmid factor versus the normal stress P/ A0 acting on the rod. At what Schmid factor value are these experimentally-measured yield loads at a minimum? Does this make sense?
A BCC mono crystal is oriented such that the direction [001] is parallel to the direction of application of the effort. If the resolved shear stress in the direction of slip is 12,000 psi, determines the magnitude of the moment applied (and that is required) to cause slippage in the steering (110)
