Material sample, for static cyclic or dynamic fatigue test, has hollow space, where free additional outer surface is turned away from space and is exposed to medium and/or application of energy

摘要

The sample (1) has an enclosed hollow space (3), where a unit for producing pressure, which is directed to the hollow space, is inserted or conducted out into or from the hollow space. A free additional outer surface (5) is turned away from the hollow space, where the free additional outer surface is exposed to the medium and/or application of energy. A kerb structure is inserted within the hollow space.
