TLDR
In this article, a method for characterisation of materials subjected to large strains beyond the levels when plastic instability occurs in standard tension tests is presented, where thin sheets of two types of hot-rolle...About:

Overview of Identification Methods of Mechanical Parameters Based on Full-field Measurements
Stéphane Avril,Marc Bonnet,Anne Sophie Bretelle,Michel Grédiac,François Hild,Patrick Ienny,Felix Latourte,Didier Lemosse,Stéphane Pagano,Emmanuel Pagnacco,Fabrice Pierron +10 more
TL;DR: In this article, the authors present several methods for constitutive parameter identification based on kinematic full-field measurements, namely the finite element model updating method (FEMU), the constitutive equation gap method (CEGM), the virtual fields method (VFM), the EGM, the equilibrium gap method, and the reciprocity gap method.

Design and fabrication of materials with desired deformation behavior
Bernd Bickel,Moritz Bächer,Miguel A. Otaduy,Hyunho Lee,Hanspeter Pfister,Markus Gross,Wojciech Matusik +6 more
TL;DR: This paper introduces an optimization process that finds the best combination of stacked layers that meets a user's criteria specified by example deformations and employs a number of strategies to prune poor solutions from the combinatorial search space.

The Virtual Fields Method for Extracting Constitutive Parameters From Full‐Field Measurements: a Review
TL;DR: The main aspects of the virtual fields method for extracting constitutive parameters from full-field measurements provided by optical non-contact techniques are recalled in the case of both linear and non-linear constitutive equations.

Applying the Virtual Fields Method to the identification of elasto-plastic constitutive parameters
Michel Grédiac,Fabrice Pierron +1 more
TL;DR: In this article, the identification of constitutive parameters governing elasto-plastic constitutive equations is addressed by using virtual fields, and a cost function is then deduced.

Characterization of the post-necking strain hardening behavior using the virtual fields method
TL;DR: In this paper, the post-necking strain hardening behavior of three sheet metals having different hardening behaviour was characterized using the virtual fields method (VFM) with Swift and modified Voce laws.

A simplex method for function minimization
John A. Nelder,R. Mead +1 more
TL;DR: A method is described for the minimization of a function of n variables, which depends on the comparison of function values at the (n 41) vertices of a general simplex, followed by the replacement of the vertex with the highest value by another point.

Inverse Problem Theory: Methods for Data Fitting and Model Parameter Estimation
TL;DR: In this paper, the least-squares (l 2 -norm) and the Minimax (l #-norm) Criterion are introduced. But they do not cover the general discrete inverse problem.

Nonlinear Continuum Mechanics for Finite Element Analysis
Javier Bonet,Richard D. Wood +1 more
TL;DR: Bonet and Wood as discussed by the authors provide a complete, clear, and unified treatment of nonlinear continuum analysis and finite element techniques under one roof, providing an essential resource for postgraduates studying non-linear continuum mechanics and ideal for those in industry requiring an appreciation of the way in which their computer simulation programs work.
