For a recently tested batch of E71T1(welded as per ASME Section II C requirements), the all weld tensile showed a YS and UTS of 83400psi with 24% elongation. The yield strength was measured by checking the gage length continuously and by the dial on the load readings itself. The material did show necking but after the yield strength was reached there was no increase in the load readings. Can the yield strength and UTS for this material be the same? What could be the possible reasons for such an occurence, I know that the yield load reading might be wrong, but any better ways of arriving at the yield strength? This testing was done on the older type machines where there is no automatic plotting of the stress-strain curve.

Todayâ€™s product development cycle is fraught with difficulties. Increased demands for complex functionality and reduced product development windows cause engineering teams to borrow practices from the IT industry, swapping outdated serial workflows for a more flexible and collaborative design method known as Agile Product Engineering.
