Abstract An empirical failure criterion is formulated astm d2938 expressing the second invariant of stress deviation at failure as a function of the first invariant of stress, key parameter, and volume.

A cooling device is incorporated, for superior control and uniformity of pressure throughout the test.

The criterion formulated from the uniaxial and triaxial test data astm d2938 predicts the strengths for biaxial compression tests.

The 2 consoles are operated independently and the failure envelope is obtained by few aastm tests single – stage with adtm application of axial astm d2938 and confining pressure at different levels.
