Grain Size and Its Influence on Materials Properties

metals, such as Fe, Mo, and Cr, we have grains produced in ferritic structures (Fig. 1) ; in face-centered cubic (FCC) metals, such as Al, Ni, Cu, and certain stainless steels, we have grains produced in austenitic structures (Fig. 2). The grains have the same shapes and are measured in the same way, but we must be careful in describing

Introduction to LRFD, Loads and Loads Distribution

Introduction to LRFD 1-8 Resistance Factors (Article 6.5.4.2) Resistance factors, φ, for the strength limit state shall be taken as follows: • For flexure φf = 1.00 • For shear φv = 1.00 • For axial compression, steel only φc = 0.90 • For axial compression, composite φc = 0.90 • For tension, fracture in net section φu = 0.80 • For tension, yielding in gross section φy = 0.95
