Identification of Johnson-Cook's Viscoplastic Model Parameters Using the Virtual Fields Method: Application to Titanium Alloy Ti6Al4V

Delphine Notta-Cuvier, Bertrand Langrand, Eric Markiewicz, Franck Lauro, Gérald Portemont

The identification of viscoplastic material parameters is addressed using a new powerful method: the virtual fields method (VFM). Contrary to classical procedures that are statically determined, the VFM is applied to heterogeneous mechanical fields. Without any hypotheses of homogeneity required,...

A Resonant-Superlinear Elliptic Problem Revisited

Mabel Cuesta, Colette De Coster

We consider the resonant-superlinear elliptic problem−∆u=λ1u+(u+)q+f(x), withDirichlet boundary conditions on a bounded regular domain ofRN. We assume that 1<q<N+1N−1,f∈Ls(Ω) withs>Nsatisfies∫Ωfφ1<0 and (λ1,φ1) is the first eigenpair of−∆onH10(Ω). We apply a non-well ordered lower and...

Lower and upper solutions for the heat equation on a polygonal domain of R2

Colette De Coster, Serge Nicaise

We consider the nonlinear periodic-Dirichlet heat equation on a polygonal domain of the plane in weighted Lp-Sobolev spaces equation presented Here f is Lp(0; T;Lpμ(Ω)-Caratheodory, where L pμ(Ω) = {v ε Lploc(Ω) : rμv ε Lp(Ω)}, with a real parameter μ and r(x) the distance from x to the set of...

Takagi-Sugeno Fuzzy Representation to Modelling and State Estimation

Mohammed Chadli, Thierry-Marie Guerra, Ivan Zelinka

This chapter shows the interest of Takagi-Sugeno (T-S) fuzzy model approach to apprehend nonlinear behaviors of physical systems and its application for observers design. From mathematical nonlinear model or experimental data, a T-S representation can be obtained using different techniques. This...

Stability analysis of switching TS models using α-samples approach

Zsofia Lendek, Jimmy Lauber, Thierry-Marie Guerra, Paula Raica

In this paper we consider stability analysis of discrete-time switching systems represented by Takagi-Sugeno fuzzy models. For the analysis we use a switching Lyapunov function defined on the switches. In order to develop stability conditions, we consider the variation of this function along...

Option pricing with constant elasticity of variance (CEV) model

Rajae Aboulaich, M. L. Hadji, Abdelilah Jraifi

In this work we propose an approximate numerical method for pricing of options for the constant elasticity of variance (CEV) diffusion model. We prove firstly the existence and uniqueness of the solution in weighted Sobolev space, and then we propose the finite element method and finite difference...

Control of Haptic Systems with Time-varying Delay

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

This paper addresses the stable implementation of high stiffness interactions of objects in the virtual environment. The virtual wall is modeled as a mechanical system including a linear spring characterized by a virtual stiffness and a damper with a virtual damping in parallel. A novel approach...

Experimental validation and critical analysis of inverse method in mass transfer using electrochemical sensor

Emna Berrich, Fethi Aloui, Jack Legrand

Rehimi et al. [1] numerically studied the frequency response of an electrochemical probe. They applied an inverse sequential algorithm of the convection diffusion equation to simulated periodic mass transfer signals in order to determine the wall shear rate. This paper presents an experimental...

Benchmarking Flexible Job-Shop Scheduling and Control Systems

Damien Trentesaux, Cyrille Pach, Abdelghani Bekrar, Yves Sallez, Thierry Berger, Thérèse Bonte, Paulo Leitão, José Barbosa

Benchmarking is comparing the output of different systems for a given set of input data in order to improve the system's performance. Faced with the lack of realistic and operational benchmarks that can be used for testing optimization methods and control systems in flexible systems, this...
