Let the stress-strain diagram for Problem 14.23 be flat-topped at a stress of 258 MPa. What is the magnitude of the strain at the root of the notch when Scc = 1.10?
Problem 14.23
In Figure 14.28a, let a = 30 mm, t = ρ = 5 mm, and the thickness of the plate be d = 12.5 mm. Let the load be P = 110 kN. If the stress-strain curve of the material is given by Figure E14.4a, determine the stress concentration factor.
