Manhani, "Influence of the testing gage length
on the strength, young's modulus and weibull modulus of carbon fibres and glass fibres," Materials Research, vol.
, elongation close to 400% of the specimen gage length
was achieved by applying a pulsed electric current to 5754 aluminum alloy specimens under tension.
strain within the gage length
can be obtained with the long-gauge FBG sensor.
Metal foil type strain gage (Type EC-AL-5-GF 1-350-L), made in Japan with gage length
5mm, width 1.4 mm, gage factor 2.1 and resistance of 350 [+ or -] 0.5 ohms were used for stainless steel and also for Delrin.
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
. In a full scale test, a large reservoir of gas supplied to the test section is needed to simulate a rupture of a gas line.
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.
The specimen is designed with the purpose of carrying out multiaxial fatigue tests so the gage length
is so short to avoid torsional buckling.
To measure the strains in the radial and tangential directions during loading, biaxial strain gages (gage length
= 2 mm; FCA-2- 11, Tokyo Sokki Co., Tokyo) were bonded on both cross sections by cyano-acrylate adhesive.
The thickness and cross-sectional gage length
were measured and recorded.
