12], elongation close to 400% of the specimen gage length was achieved by applying a pulsed electric current to 5754 aluminum alloy specimens under tension.
For normal quasi-static tensile tests without electric current (baseline tests) and quasi-static tensile tests with a single pulse of electric current, typical tensile specimens with a 10 mm gage width and 50 mm gage length were fabricated along the rolling direction of the sheet according to ASTM-E08.
Metal foil type strain gage (Type EC-AL-5-GF 1-350-L), made in Japan with gage length
5mm, width 1.
The specimen was designed with the purpose of carrying out multiaxial fatigue tests so the gage length
was so short to avoid torsional buckling.
Price (1975) studied the effect of gage length
on the stiffness and strength of sweetgum flakes.
This assures near constant energy along the length of the specimen gage length
No extension meter was available, so to measure elongation, a 25 mm gage length
was marked on a sample of each material and a ruler held next to the sample during testing.
The gage length
of the tensile specimen can vary from standard to standard, and this will affect measurement of elongation.
This is true matching - not just gage design or gage length
, but the whole bit including the cutting structure," Reese said.
The specimen is designed with the purpose of carrying out multiaxial fatigue tests so the gage length
is so short to avoid torsional buckling.
The thickness and cross-sectional gage length
were measured and recorded.
Specimens with enhanced orientation levels distributed more uniformly along the gage length
tended to exhibit higher tensile strengths.
