When selecting a universal material testing machine , the customer will ask what function the machine has. Today we will summarize the nouns that appear when the testing machine is tested:

1. Bending : The compressive or tensile forces applied to the ends of a specimen to bend the specimen.

2. Impact energy: The energy required for a specimen to be ruptured by an impact load in an impact test of an impact tool. The alternative terms are impact value, impact strength, impact resistance, and energy absorption.

3. Impact strength: In the impact test, the energy required for the specimen to break under a relatively high speed impact load in a very short period of time is a reflection of the toughness of the material. Also known as impact energy, impact value, impact resistance and energy absorption.

4. Impact test: A method of determining the characteristics of a specimen subjected to impact by external forces during flexural, tensile or torsional tests, usually by measuring specimens subjected to such tests as simple beam impact tests, cantilever impact tests and tensile impacts. The energy absorbed by a single pendulum impact in the test. Impact tests also have multiple impacts that increase the strength of the specimen, such as drop weight impact tests and repeated impact impact tests. Impact resilience and rebound stiffness were measured in a nondestructive impact test.

5. Twist test: Test method for determining the flexibility of a wire.

6. Modulus: The ratio of stress to strain of a material under stress. Corresponding to different stress states, there are different titles. Can replace the elastic modulus. Within the limit of elasticity, the deformation of an object caused by the action of an external force is proportional to the external force received. Deformation varies with the direction of the force, and the force that causes the object to stretch is called "tension" or "tension."

7. Elongation: It is an index that describes the plastic properties of a material.

8. Peel test: The process of separating a rubber coating or a rubber layer from a substrate (such as metal or cloth) or another rubber layer under the action of an external force. The difference from pull-off is that the peeling starts from the edge of the interface, and the pull-off is the force of the entire adhesive surface at the same time. According to the peeling force and the angle between the adhesive surface, it can be divided into 180° peeling and 90° peeling.

9. Shear force test: Shear is the relative error of the cross-section of a material in the direction of the action of the external force under the action of a pair of closely spaced lateral external forces (ie, forces parallel to the acting surface) that are close together, of the same size, and are pointing at opposite directions. Dynamic deformation phenomenon. The force that can cause shear deformation of a material is called shear or shear force. The section where shear deformation occurs is called a shear plane.

10. Fatigue test: Under the cyclic loading of materials or parts and components, local permanent damage will occur at some point or some points, and cracks will be formed after a certain number of cycles, or the crack will be further expanded until completely broken.

11. Static bending strength test: The static bending strength is the ratio of the bending moment and the bending section modulus of the test piece when the maximum load is applied.

The above is the introduction of common terms used in the general use of universal material testing machine to do the test, mainly to do the tensile test, tear test, peel test, bending shear force, three point bending and so on.
