Isogeometric analysis of nearly incompressible large strain plasticity
TL;DR: In this article, the behavior of NURBS-based Isogeometric analysis on problems of large deformation plasticity was studied, and it was shown that the concept of "mesh locking" is not a relevant issue for higher-order NurBS elements.

A variational constitutive model for slip-twinning interactions in hcp metals: Application to single- and polycrystalline magnesium
Yingrui Chang,Dennis M. Kochmann +1 more
TL;DR: In this article, a constitutive model for hcp metals is presented based on variational constitutive updates of plastic slips and twin volume fractions and accounts for the related lattice reorientation mechanisms.

Isogeometric Kirchhoff-Love shell formulation for elasto-plasticity
TL;DR: In this article, an isogeometric thin shell formulation allowing for large-strain plastic deformation is presented, where the constitutive equations are evaluated at different integration points through the thickness, allowing the use of general 3D material models.

Linear and nonlinear programming
David G. Luenberger,Yinyu Ye +1 more
TL;DR: Strodiot and Zentralblatt as discussed by the authors introduced the concept of unconstrained optimization, which is a generalization of linear programming, and showed that it is possible to obtain convergence properties for both standard and accelerated steepest descent methods.

Consistent tangent operators for rate-independent elastoplasticity☆
Juan C. Simo,R.L. Taylor +1 more
TL;DR: In this paper, it is shown that consistency between the tangent operator and the integration algorithm employed in the solution of the incremental problem plays crucial role in preserving the quadratic rate of asymptotic convergence of iterative solution schemes based upon Newton's method.

On numerically accurate finite element solutions in the fully plastic range
TL;DR: In this paper, a general criterion for testing a mesh with topologically similar repeat units is given, and it is shown that only a few conventional element types and arrangements are suitable for computations in the fully plastic range.
