What Is a Tensile Tester?
A Tensile tester is a device that measures the change in a sample when a tensile load is applied to it.
Tension generates stress and strain. The relationship between tensile stress, tensile strain, Young's modulus, Poisson's ratio, etc., are calculated.
The parameters obtained from tensile testing are called mechanical properties and play an essential role in determining the strength and durability of molded products.
Tensile tests are often performed on dumbbell specimens following JIS standards. In some cases, tests are conducted using non-standard shapes.
Uses of Tensile Testers
Tensile testing can measure various parameters, some of which are introduced here.
- Young’s Modulus Young's modulus is the ratio of stress to strain. Young's modulus indicates a material's bendability (difficulty), and a higher Young's modulus indicates that the material is harder and more difficult to bend.
Steel used for construction materials is one with a high Young's modulus.
- Poisson’s Ratio Poisson's ratio is the ratio of strain in the direction of applied force (longitudinal strain) to strain perpendicular to the direction of applied force (transverse strain).
If Poisson's ratio is 0.5, there is no volume change due to deformation. For materials such as rubber, the lateral strain decreases as the material is pulled, so the value is close to 0.5.
Principle of Tensile Testers
Various parameters can be calculated by applying a tensile load to a specimen and measuring the result until the material breaks.
A plot of stress versus strain obtained from the measurement gives the parameter's value.
The initial measurement is proportional to the strain. The limit at which the balanced relationship holds is called the proportional limit.
If we add more stress from the proportional limit, the strain will remain at a certain point. The limit point at which no strain remains is called the elastic limit. Beyond the elastic limit is the yield point. When the yield point is exceeded, the stress drops while the strain remains.
If the tensile strength is continued after that, the stress increases again. The maximum stress is called tensile strength, and the material finally breaks.
The proportional limit, elastic limit, yield point, and tensile strength can be calculated directly from the stress/strain plot.
Young's modulus, Poisson's ratio, etc., can be calculated using the plots.
Depending on the parameters to be obtained and the specimen's material, static extensometers, dynamic extensometers, and long extensometers are used.
How to Read a Tensile Tester
A tensile tester is used to measure the stress-strain curve (Stress-Strain Curve) since the primary purpose of a tensile tester is to test the load in the tensile direction. However, many of today's testing machines can measure in compression and tensile directions (universal testing machines).
Tensile testers" are sometimes referred to as materials testing machines, universal testing machines, load testing machines, and so on. Amsler-type testing machines, Instron, Autograph, Tensilon, and other brand names are also used.
Tensile Tester Units
Tensile testers use a load cell to measure force. The SI unit of "force" is expressed in "N" newtons. Depending on the capacity of the load cell, "mN" or "kN" may be used.
N" Newton is the value obtained by multiplying the mass by the acceleration of gravity. If the gravitational acceleration of the measurement location is known, the mass (kg) can be measured with a load cell. If you know that the gravitational acceleration at the location is 9.8 m/s2, you can measure an object, and if the measurement value shows 9.8 N, you can say that the object's mass is 1 kg. Suppose there is a weight weighing 1 kg, and the acceleration of gravity at that location is 9.8 m/s2. In that case, we can calibrate the readout to 9.8 and say the readout is 1 kg = 9.8 N. Gravitational acceleration is a different value depending on latitude, longitude, and elevation, so force calibration should be performed at each location. In Japan, Wakkanai, and Kagoshima, there is a difference of almost 1.2g when a 1kg mass is measured with the same load cell scale. (The acceleration of gravity according to GSI is 980642.6 mGal in Wakkanai and 979471.18 mGal in Kagoshima.)
Also, "N" newton was used as "kgf" before SI units came into effect, but due to the revision of the Measurement Law, "N" newton is no longer available in Japan since October 1999.
