A Newton-Schur alternative to the consistent tangent approach in computational plasticity
(2007) In Computer Methods in Applied Mechanics and Engineering 1996(7). p.1169-1177- Abstract
- We introduce a Newton-Schur alternative to the consistent tangent approach in plasticity computations and show that the structure of the consistent tangent approach is preserved in the new Newton-Schur approach. However, the local constitutive iterations used in the conventional computational plasticity analyses are eliminated when using the Newton-Schur approach. Two numerical examples are presented which illustrate the efficiencies gained by the new approach.
