The strength coefficient and strain-hardening exponent of a certain test metal are 500MPa and 0.25 respectively. A cylindrical specimen of the metal with starting diameter = 58 mm is stretched. If the average flow stress on the part is 375 MPa determine the final diameter of the specimen.

B 3.2 A Q2. σ (Pa) σo (Pa) 780,000,000 This tutorial exercise assesses fundamental understanding of the creep and stress relaxation response of metals subjected to either constant load or constant strain. It is designed to reinforce learning of principles set out in your current stage 2 lecture notes in "Creep Failure and Stress Relaxation" and to build on knowledge previously presented in the stage 1 module "Solids & Structures". C Q3. t (hr) For further information you may refer to Chapter 21 (Creep and Viscoelasticity) of Benham, Crawford, and Armstrong (1996), 2nd Ed. Q1. A typical graph of strain (e) versus…

How can I solve for the %0.2 offset strain and the calculated stress? Original diameter : 6mm Original length : 30mm Fracture diameter : 4.54mm

A tensile test was performed on a metal specimen with a diameter of 1/2 inch and a gage length (the length over which the elongation is meas- ured) of 4 inches. The data were plotted on a load-displacement graph, P vs. AL. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P/AL = 1392 kips/in. What is the modulus of elasticity? BI
