5 Common Errors in Tensile Testing | 2017-10-31

Oct 31, 2017 · 5. Uncompensated system deflection. Travel measurements, required in stress-strain curves, elongation, and most other tensile tests, are subject to errors due to system deflection. These offsets originate from both the load cell and the test frame. Strain gage-based load cells, by their nature, deflect slightly as a load is applied.

Overview of the standard problems of the ATLAS facility

Instead of mixing, azimuthal temperature stratification was predicted even in the lower down-comer region. This incorrect prediction seems to be due to a limitation of the one-dimensional code to treat ECC mixing. The NRC’s calculation, where three-dimensional modeling was used in the reactor vessel region, showed better mixing than the others.
