Consistent tangent matrices for substepping schemes
(2001-06)
Article
Accés obertA very simple and general expression of the consistent tangent matrix for substepping time-integration schemes is presented. If needed, the derivatives required for the computation of the consistent tangent moduli can be ... -
Numerical differentiation for local and global tangent operators in computational plasticity
(2000)
Article
Accés obertIn this paper, numerical di¿erentiation is applied to integrate plastic constitutive laws and to compute the corresponding consistent tangent operators. The derivatives of the constitutive equations are approximated by ... -
