  • Patent number: 4192194
    Abstract: A thin-wall tube specimen is biaxially tested for stress analysis by applying compressive axial stress and either internal surface pressure or external surface pressure to the specimen. Torsion is not required. The sample is positioned between platens which are assembled inside a pressure collet. Axial compressive stress is applied through the platens to the specimen, and hydraulic pressure is applied through the assembly to the internal and external cylindrical surfaces of the specimen. Rubber bladders may be employed when applying the surface pressures.
