Under internal pressure is defined as the inherent pressure that a fabric or a system exerts on its environment and thus expansion aims of himself. The most important example of an internal pressure is the saturation vapor pressure , which is inherent in every liquid and solid. The system concept is, however, this very broad and it is for example also in cabin pressure , boiler pressure , cavity pressure and tire pressure to internal pressures.

The antagonist of internal pressure is the external pressure , which acts on the system from the outside and strives to compress it .
