Strength Test Types
Purpose of Strength Tests
The main purpose of strength testing is measuring the amount of deformation under load on an object.
Static Test
Static testing refers to a method of strength testing in which a load is applied to a test piece at low speed. Various tests can be conducted depending on how the load is applied to the test piece.
| Tensile Test | |
|---|---|
| Compression Test | |
| Flexural Test | |
| Peeling Test |
Dynamic Test
Dynamic testing refers to a method of strength testing in which specimens are subjected to loading at high speeds. This method can be classified into the following three types.
| Impact Test | Continuous loading at very high speeds. |
|---|---|
| Fatigue Test | Continuous loading for a given period of time until rupture. |
| Durability Test | Continuous loading until a given number of cycles. |

Hardness and Viscosity Tests
There are also the following types of strength tests. In both cases, the appropriate test equipment must be selected according to the property values that need to be obtained.
- Hardness test: a test to determine the hardness of a material. Hardness is defined differently for each testing method and the values obtained depend on the testing equipment used.
- Viscosity test: a test to measure the fluidity or viscosity of a material. These characteristic values are important when making products from molten materials, such as in injection molding.
