Abstract Based upon the strength criterion proposed by Gol'denblat and Kopnov, the second-, fourth-, and sixth-rank strength tensors in the three-dimensional case have been determined for each of the crystal classes from consideration of invariant transformations of the strength function. A cubic polynomial form has been proposed as an improved strength criterion for anisotropic brittle materials by using the constitutive laws in continuum mechanics. The methods of determination of the strength coefficients and the strength envelope in the biaxial stress state for graphite are presented in detail by relating the cubic polynomial strength criterion to the experimental test data. Numerical examples are presented to show that the theoretical and experimental results are in good agreement. A comparison with the results previously published is presented.
