WebSep 2, 2024 · This stress may be calculated for any point on the load-deflection curve by the following equation: S = 3 P L / 2 b d 2. where S = stress in the outer fibers at midspan, MPa; P = load at a given point on the load-deflection curve; L = support span, mm; b = width of beam tested, mm; and d = depth of beam tested, mm. WebWhat is critical buckling stress? The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally. The critical load puts the column in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. cindy bownWebFor beam buckling, we're interested in the second case, i.e. cos (kL)=0.
