Mechanical design of a heterogeneous test for material parameters identification
TL;DR: In this paper, a shape and boundary conditions optimization process was developed based on a quantitative indicator rating the strain field information and used as a cost function for guiding the test design, which led to an inhomogeneous strain field promoting the mechanical behavior characterization of thin metallic sheets under several strain paths and strain amplitudes.

An endochronic plasticity model for finite strain deformation of powder forming processes
TL;DR: In this article, the numerical modeling of powder-forming process is simulated by a finite element analysis using a density-dependent endochronic plasticity model, and the numerical schemes are examined for efficiency in the modeling of a multi-level and tip shape powder compaction component.

A structural nonlinear analysis workspace (SNAW) based on meshless methods
TL;DR: This SNAW development interfaces meshless analysis code with MSC/PATRAN for pre- and post-processing using graphical menu-driven functionalities and effectively deals with large structural deformations that usually lead to mesh distortion and solution divergence in finite elements.

A new polyhedral element for the analysis of hexahedral-dominant finite element models and its application to nonlinear solid mechanics problems
TL;DR: In this article, a tetrahedral subdivision of polyhedral domains by a centroid-based subdivision technique is proposed to solve large deformation problems of hyperelastic and elastic-plastic materials.

Numerical simulation of finite strain viscoplastic problems
TL;DR: A large strain elastoplastic constitutive model based on hyperelasticity and multiplicative decomposition of deformation gradient tensor is extended to viscous case, in a framework similar to the one that has been proposed by Ponthot in an hypoelastic context, and a very useful framework can be obtained.

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.
