Werkstoffprobe fuer Ermuedungsversuche

DE 102005054331 A1 UPAB: 20071024 NOVELTY - 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. USE - Used for static cyclic or dynamic fatigue test in presence of poisonous explosion dangerous expensive medium and/or application of energy e.g. thermal energy and electromagnetic energy, for determining material characteristics (all claimed). ADVANTAGE - The material sample can be directly exposed to liquid, solid or gas like medium, thus determining loading capacity and limitation of life span in close to reality operating conditions, and hence avoiding the need to meet the technical expenditure sealing and protection requirements. The necessary measures can be realized in a technically simple manner and facilitate cost saving
