Abstract An empirical failure criterion is formulated by expressing the second invariant of stress deviation at failure as a astm d2938 c2938 the first invariant of stress, key parameter, and volume. The 2 consoles are operated independently and the failure envelope is obtained by satm individual tests single – stage with automatic application of axial load and confining pressure at different levels.
