Detection of various physical test in the field of force and energy, a noun
In the process of test, often will encounter some nouns, here give you a little part of compiled.
1. Bending: on the ends of the sample to make sample bending compression force and tensile force.
2. The impact energy, impact tools impact test, the sample impact load and the energy needed to power a burst, the alternative term impact value, the impact strength, impact resistance and energy absorption.
3. The impact strength, impact test, the sample in a very short period of time by relatively high speed impact load and the energy needed to power a burst, is a reflection of the material toughness. Also called impact energy, impact value, resistance to impact and energy absorption.
4. The impact test: test sample in bending, stretching, or reverse, when subjected to external forces into goods characteristics, the method of beam is usually measured sample by such as impact test, cantilever beam impact test and tensile impact test of single pendulum impact absorbing energy. Impact test samples can also have the strength increasing of repeated impact, such as drop hammer impact test and repeated impact test. Impact resilience and shore hardness is measured in no destructive impact test.
5. The distortion test: test method for determination of flexible metal wire.
6. Modulus: the ratio of the material in the stress state of stress and strain. Corresponding to different stress state, there is a different appellation. Alternative elastic modulus. Within the elastic limit, the object by the effect of external force and deformation is proportional to the force of. Deformation and varies with the direction of the force, make the object extension force called "pull" or "tension".
7. Elongation: describes material plastic performance indicators.
8. Peel test: rubber or rubber coating layer under the action of external force from the base material (such as metal or cloth) or a rubber layer on the separation process. And pulled away from the different is: stripping began from the edges of the interface, and avulsion is the bonding surface stress at the same time. According to the strip tension and the Angle between bonding surface is different, also can be divided into 180 ° peel and 90 ° peel.
9. The shear stress test: shear is within easy reach of a pair, same size, pointing to the opposite lateral force (i. e., the parallel to the force), the material of cross section along the direction of the external force occurs relatively faulting and deformation phenomenon. To make the material produces shear deformation force is called the shear force and shear force. The cross section is called the shear plane shear deformation.
10. Fatigue test: materials or parts and components under cyclic loading, at some point or some point partial permanent damage, and in certain cycles after crack, crack further extend until completely or fracture phenomenon.
11. Insertion force test: terminal and the line between tension, refers to the riveting pressure strength between the two, the conductor cross-sectional area of the size and wire. Insertion force is terminal and (combination) terminal or insert force between the insert and pull out.
12. Static music intensity test: static music intensity is to determine the specimen when the maximum load effect of the ratio of the bending moment and bending modulus.
