10KN 20KN 90 Degree Peel Strength
Universal Testing Machine/Tester
Test principal
In the plastic material represented by low-carbon steel, a large transverse deformation can be generated in the axial compression, but due to the friction between the two end surfaces of the specimen and the support plate of the testing machine, the transverse deformation is restrained, so that the middle part of the specimen has a significant bulging.
The elastic modulus and yield point of plastic materials in compression are the same as those in tension, but when they reach the yield stage, they are not as obvious as in tensile test, therefore, it needs to observe carefully to determine the load capacity FsC. When the loading continues, the compression capacity of the sample increases with the increase of the cross section area, and the curve continues to rise. Unless the specimen is over-bulged and deformed, resulting in the cracking of the cylinder surface, the plastic material will not be subjected to compression failure. Therefore, the compressive strength of plastic materials is not measured, but the compressive strength is usually considered to be equal to tensile strength.
Because the plastic deformation of the brittle metal material represented by cast iron is very small, although there is end face friction, the bulging effect is not obvious, but when the stress reaches a certain value, the specimen breaks in the direction of about 450 × 550 with the axis. This is due to the fact that the shear strength of brittle materials is lower than that of compressive strength, so that the specimen is cut off.
