Experiments to explore the fracture and deformation of ATJ-S graphite under multiaxial stresses are described. The program included additional fracture tests in biaxial tension at 2000F an analytical evaluation of the applicability and limitations of biaxial test data tests at room temperature under triaxial stress states to measure the effects of multiaxiality on strain and some biaxial experiments at room temperature to further explore the nature of biaxial softening the occurrence of unexpectedly large strains in biaxial tension.
