A tensile bar is machined so that the diameter at one location is 1% smaller than that for the rest of the bar. The bar is tested at high temperatures, so strain-hardening is negligible, but the strain-rate exponent is 0.25. When the strain in the reduced region is 0.20, what is the strain in the larger region? A tensile bar is machined so that the diameter at one location is 1% smaller than that for the rest of the bar.

The strainhardening is negligible which implies that the material follows a powerlaw stressstrain re... View the full answer
