摘要：

The present paper focuses on the discussion of a set of rational criteria for the selection of the damage parameter. The paper considers scalar, second-, fourth-, and six-order tenser representations of damage and evaluates the accuracy with which they approximate exact, micromechanical solutions. Considerations of geometrical, stiffness and failure criteria favor the selection of effective stiffness as being the most appropriate choice for the damage parameter.
