Clustering approach in maintenance of capillary railway network.

Danijela Đorić, Abdessamad Ait El Cadi, Said Hanafi, Nenad Mladenovic, Abdelhakim Artiba

Maintenance optimization of railway infrastructure includes several kinds of aspects, such as safety, economic, operational, organization and regulatory issues. Among them the regulatory issues, that are fixed, increase the maintenance costs significantly. This is especially true in so-called…

Iterative aggregation and disaggregation algorithm for pseudo-polynomial network flow models with side constraints

François Clautiaux, Said Hanafi, Rita Macedo, Marie-Emilie Voge, Cláudio Alves

This paper develops a general solution framework based on aggregation techniques to solve NP-Hard problems that can be formulated as a circulation model with specific side constraints. The size of the extended Mixed Integer Linear Programming formulation is generally pseudo-polynomial. To…

Four-dimensional locally strongly convex homogeneous affine hypersurfaces

Abdelouahab Chikh Salah, Luc Vrancken

We study four-dimensional locally strongly convex, locally homogeneous, hypersurfaces whose affine shape operator has two distinct principal curvatures. In case that one of the eigenvalues has dimension 1 these hypersurfaces have been previously studied in Dillen and Vrancken (Math Z 212:61–72,…

An <em>hp</em>-FEM for Singularly Perturbed Transmission Problems

Serge Nicaise, Xenophontos Christos

We perform the analysis of the hp finite element approximation for the solution to singularly perturbed transmission problems, using Spectral Boundary Layer Meshes. In [12] it was shown that this method yields robust exponential convergence, as the degree p of the approximating polynomials is…

Macro-modeling of the strength and failure of multi-layer multi-steel grade spot welds: Connector formulation, assembly model and identification procedure

Rim Chtourou, Nicolas Leconte, Fahmi Chaari, Grégory Haugou, Eric Markiewicz, Bassem Zouari

The aim of this paper is to investigate the mechanical strength and the failure of three-sheet multi-steel grade Resistance Spot Welded assemblies (RSW) using experimental and numerical tests. A macroscopic modeling approach, using three connector elements, dedicated to the crashworthiness analysis…

Hot ductility and flow stress of AISI 4130 and 52100-type steels

Damien Barbier, Jean-Dominique Guerin, Mirentxu Dubar, Vincent Benard, Sébastien Bonneau, Eli Saúl Puchi-Cabrera

The present communication reports the main findings of an investigation that has been conducted in order to examine the ductility of both the AISI 4130 and 52100 steel grades, in a wide range of temperatures, spanning from room temperature up to 1250 °C, deformed in tension at strain rates of…
