How a compression test is performed

At Servosis, we have all the necessary materials to carry out a optimal compression test.

Another of the tests you will need for successful quality control is the Compression test. This test determines the resistance of a material to compressive stress or load. Although it is less used than, for example, the tensile testThis practice is commonly used in concrete or cement and even to evaluate the durability of finished parts.

The process consists of introducing a cylindrical specimen of the material to be tested into special presses. Once there, the cylinder receives a higher pressure following the pre-established regime until it breaks, and all the necessary data are recorded on the press gauges. During the process, the stress curvefrom which we obtain the three main characteristic points:

  • The yield limit, the point at which the material enters the state of yield, causing irreversible deformation of the specimen.
  • The ultimate strength limit or breaking point, which represents the maximum stress a material can withstand before breaking.
  • The breaking point, which indicates the exact stress at which the material breaks.

From two of the above three data, the compressive strength limit can be calculated by means of the following formula:

бc= Pc / So (kg/cm²)

бc: Ultimate strength limit

                                                                             Pc: The breaking point in kg

So:Cross-sectional area of the specimen in cm²
