Multiaxial Response of ATJ-S Graphite

Abstract

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).
