A test apparatus for measuring the multiaxial strength of circular plates was developed and experimentally verified. Contact and frictional stresses were avoided in the highly stressed regions of the test specimen by using fluid pressurization to load the specimen. Both isotropic plates and single crystal NiAl plates were considered, and the necessary strain functions for anisotropic plates were formulated. For isotropic plates and single-crystal NiAl plates, the maximum stresses generated in the test rig were within 2% of those calculated by plate theory when the support ring was lubricated.
