Definition - What does Compression Force mean?
Compression force is the force generated from compressing an object or substance. When shearing forces are aligned into each other, they are called compression forces. Compression force is used to power everything from compression brakes to hand tools. The compressive strength of materials and structures is an important engineering consideration.
Compression force can be visualized by placing an object on a spring. When the spring is compressed and then released, the object is ejected into the air. This is a result of the compression force that is generated from compressing the spring.
Corrosionpedia explains Compression Force
Compression force is force acting on a body, compressing it. The application of a compression force to an object causes it to become squashed or compacted. Some solid materials like stone and ceramics are able to withstand very large compressive forces with very little measurable deformation, which make them a suitable building material for the construction of high walls and columns.
Every material suffers some deformation when put under compression, even if imperceptible, that causes the average relative positions of its atoms and molecules to change. The deformation may be permanent, or may be reversed when the compression forces disappear. In the latter case, the deformation gives rise to reaction forces that oppose the compression forces, and may eventually balance them.
The compressive forces may be applied in multiple directions; for example inwards along the edges of a plate or all over the side surface of a cylinder, so as to reduce its area (biaxial compression), or inwards over the entire surface of a body, so as to reduce its volume.
It is the force required to achieve maximum shielding effectiveness. The higher the pressure or compression force, the lower the impedance. A minimum closure force is recommended to obtain low surface contact resistivity and good shielding. Minimum closure force is that pressure required to break through corrosive and oxide films to make a low-resistance contact.
