# Standard Gauge Length Tensile Test Specimen

Standard Gauge Length Tensile Test Specimen. To conduct the tensile test dimension and shape of specimen depends upon the shape and size of the original material. The tensile specimen is prepared to evaluate yield strength. tensile strength. elongation and reduction in cross sectional area.

The tensile specimens were round with a diameter of either 6 mm (m10) or 8 mm (m12) in the gauge length lo. The tensile specimen is prepared to evaluate yield strength. tensile strength. elongation and reduction in cross sectional area. Distance between gauge points at fracture = 95 mm;

The standard gauge length. was calculated using the following formula for proportional tensile specimens (eq. Such approximation is only valid if the difference.

Previous studies on the tensile behaviour of notch specimen were mainly measured by the extensometer [4.22.28]. Test pieces are standardised in order that results are reproducible and comparable as shown in fig 2.

M10 and m12 are the standard names of round tensile specimens and refer to the thread size of the tensile specimens (i.e. Full section specimens shall elevation of the measured yield strength.

Gauge length to width ratio ( 1. 2 and 4 ). which meant high. Figure illustrate schematically the sample is tested in tension.

More prominent disparities mainly be cause of their low. Hounsfield tensometer is a small machine and widely used for tensile test in research laboratories.

Specimens are said to be proportional when the gauge length. l 0. is related to the original cross sectional area. a 0. expressed as l 0 =k√a 0. Small size specimens are cut from

#### Percentage Elongation On Standard Gauge Length.

Full section specimens shall elevation of the measured yield strength. F is the uniaxial tensile force applied. (1). l 0. w 0 and t 0 are the initial gauge length. width and thickness of the test specimen respectively.

#### A Tensile Test Uses A Specimen Gauge Length Of 100.00Mm And Cross Sectional Area Of 40.00Mm^2.

The tensile specimens were round with a diameter of either 6 mm (m10) or 8 mm (m12) in the gauge length lo. This specimen is gripped in jaws of universal testing. According to din standard. gauge length=11.2(sqrt{a}). where a denotes the cross section area of specimen used under testing.

#### The Standard Gauge Length. Was Calculated Using The Following Formula For Proportional Tensile Specimens (Eq.

The three specimen geome tries they considered showed. 10 and 12 mm. respectively). When the tension test is started and specimen a or specimen b is pulled. the strain is uniform along the gauge length up to the point at which the maximum force is reached and the onset of necking occurs.

#### Figure Illustrate Schematically The Sample Is Tested In Tension.

The gauge length of the tensile specimens was covered by the weld nugget. as shown in fig. During test. a max load of 16kn with gauge length of 101.00mm. Previous studies on the tensile behaviour of notch specimen were mainly measured by the extensometer [4.22.28].

#### Small Size Specimens Are Cut From

Normally 4d will give you a bit higher elongation. Tensile test specimen as per the is standard gauge length (lg) will be given as follows. lg = 4 ¾ # w he re. a is the cross section area. Test pieces are standardised in order that results are reproducible and comparable as shown in fig 2.
