Analogue Tensile Testing Machine

Analogue Tensile Testing Machine

Analogue tensile testing machines are used for measuring the tensile strength of various materials. This measurement is done by taking a specimen of the material to be used and subjecting it to constant and controlled tension until failure. The results of the tensile strength test determine the usability of the tested materials for their requisite purpose. Analogue tensile testing machines are widely used in various sectors such as construction, automotive and many more to ascertain how the materials being used will react to various forces and stresses during their functional life.

These testing machines have the ability to perform tests on a large number of materials. These machines are ideal for all isotropic substances( isotropic means having uniform properties in all directions, like metal and glass). Easy to use and long lasting, the  machines are available in various specifications and at market competitive rates.

Properties That are Tested by Analogue Tensile Testing Machines

Ultimate tensile strength

Maximum elongation

Reduction in area

From the Above Three Parameters Another Set of Secondary Properties Can Also be Determined, These are,

Young's modulus

Poisson's ratio

Yield strength

Strain hardening attributes

A Summary of The Test Specimen That is Tested Through an Analogue Tensile Testing Machine :

The test specimen of a metal should have two shoulders and a Gage section in between. The design of the specimen should be such that the shoulders are large and easily grippable while the Gage section has a smaller cross sectional area so that deformation can occur during the tensile strength test. The specimen's cross sectional area of the Gage section is lesser relative to it's shoulders for ensuring that any deformation that occurs should be localized to the Gage section only. The distances between ends of the Gage section and the shoulders should be great enough to make sure the larger ends should not constraint deformation within the Gage section.

Advantages of Analogue Tensile Testing Machines Over Mechanical Testers

The machines have a digital display showing the precise load and elongation, this eliminates human errors in reading load and elongation measurements.

More accurate results due to high resolution of load cells.

The machines have a longer life span due to less moving parts.

Better test results due to less friction inertia.
