abstract:In mathematics, a dissipative operator is a linear operator A defined on a linear subspace D(A) of Banach space X, taking values in X such that for all λ > 0 and all x ∈ D(A)
According to the generalized normalityrule, the tangent stiffness operatorofelastoplastic material coupled with damage is derivedfrom thestatepotentialand the dissipativefunctions.
