Isochoric In Situ Mechanical Testing of Materials

      
Application Number 19222080
Status Pending
Filing Date 2025-05-29
First Publication Date 2025-12-11

Abstract

An in situ chamber assembly for mechanical testing of materials. The in situ chamber assembly includes a pressure vessel having first and second end caps. A pull rod extends through the pressure vessel and has a sliding and sealing relationship with the first and second end caps. A specimen retainer assembly is disposed within the pressure vessel. The specimen retainer assembly including a fixed portion coupled to the pressure vessel and a movable portion coupled to the pull rod. At least one specimen is positioned between the fixed portion and the movable portion of the specimen retainer assembly such that movement of the pull rod relative to the pressure vessel applies a load on the at least one specimen. In operation, movement of the pull rod relative to the pressure vessel occurs isochorically and isobarically.
