| Title | Consistent Linearization of Incrementally Objective Algorithms and Comparison with ABAQUS |
| Year | 1997 |
| Abstract | A methodology for explicit formulation of the tangent stiffness matrix consistent with incrementally objective algorithms for integrating finite deformation kinematics and with closest point projection algorithms for integrating material response is developed in the context of finite deformation plasticity. Numerical experiments illustrate an excellent performance of the proposed formulation and reveal its computational advantage over inconsistent algorithms commonly used in practice. |
