Consistent tangent matrices for density-dependent finite plasticity models
(2001-09)
Article
Accés obertThe consistent tangent matrix for density-dependent plastic models within the theory of isotropic multiplicative hyperelastoplasticity is presented here. Plastic equations expressed as general functions of the Kirchhoff ... -
Numerical differentiation for local and global tangent operators in computational plasticity
(1998-09)
Report de recerca
Accés obertIn this paper, numerical differentiation is applied to integrate plastic constitutive laws and to compute the corresponding consistent tangent operators. The deriva- tivesoftheconstitutive equationsareapproximatedbymea ...
