What is Compression Force? | Tekscan

Compression force (or compressive force) occurs when a physical force presses inward on an object, causing it to become compacted. In this process, the relative positions of atoms and molecules of the object change. This change can be temporary or permanent depending on the type of material receiving the compressive force. There can also be different results depending on the direction or ...
