Questioning numerical integration methods for microsphere (and microplane) constitutive equations

•Cubature methods for microsphere and microplane constitutive equations are studied.•Three different formulations are compared by computing large strain invariants.•The classical Bažant and Oh 42 points algorithm is revealed ineffective.•For the two other methods, a very large number of integration...
