Shape optimization of the X0-specimen: theory, numerical simulation and experimental verification
TL;DR: In this article, the gradient-based shape optimization of the biaxial X0-specimen has been applied to different loading conditions persisting the question if relevant stress states could be reached by optimizing the geometry.

A finite–strain elastoplasticity material model for ETFE membrane structures
Marianna Coelho,Deane Roehl +1 more
TL;DR: In this article, a numerical model for the simulation of the behavior of membrane structures fabricated using ethylene tetrafluoroethylene (ETFE) materials is presented, and the use of von Mises yield criteria is suggested for ETFE foils.

Finite Strain Elastoplasticity: Consistent Eulerian and Lagrangian Approaches
TL;DR: A unified framework of Eulerian rate-type constitutive models for large strain elastoplasticity is developed in this paper which assigns no preference to the choice of objective corotational rates.

Fracture parameter for thermoinelasticity
D. A. Wagner,Juan C. Simo +1 more
TL;DR: In this article, a path domain independent integral, S, that equals the energy release rate for an extending crack in a thermoinelastic field is presented, which can be calculated from finite element results and describes how S can be obtained from experiments.

Sheet metal forming analysis using a large strain anisotropic multiplicative plasticity formulation, based on elastic correctors, which preserves the structure of the infinitesimal theory
TL;DR: A novel large strain formulation for anisotropic hyperelasto-plasticity is implemented in a user subroutine of the commercial program ADINA to perform sheet metal forming simulations, testing the robustness and suitability of the model for industry, as well as its accuracy.

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.
