Some improvements for determining the hardness of homogeneous materials from the work-of-indentation

Didier Chicot, Michel Yetna N'Jock, Francine Roudet, Xavier Decoopman, Mariana H. Staia, Eli Saúl Puchi-Cabrera

In this work, the total and plastic hardness of a variety of materials were determined from the work-of-indentation. We show that by taking into account the influence of the tip defect, both the total and plastic hardness have the same values and that the hardness-load dependence is considerably...

An Iterative Greedy Insertion Technique for Flexible Job Shop Scheduling Problem

Azzedine Bekkar, Oualid Guemri, Abdelghani Bekrar, Nassima Aissani, Bouziane Beldjilali, Damien Trentesaux

This paper studies the problem of scheduling in a flexible job shop. A greedy heuristic is developed to solve precisely the sequencing (allocation) problem. The principle of this approach is to iteratively insert operations on the machines until the objective of minimizing the Cmax (makespan) is...

Finding a stabilizing switching law for switching TS models

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

This paper considers the stabilisation of switching nonlinear models by switching between the subsystems. We assume that arbitrary switching between two subsystems is possible once a subsystem has been active for a predefined number of samples. We use a Takagi–Sugeno representation of the models...

Integer Programming Based Approaches for Multi-Trip Location Routing

Rita Macedo, Cláudio Alves, José Valério De Carvalho, Said Hanafi, Nenad Mladenovic, Bruna Ramos

The multi-trip location routing problem consists in selecting the depots to open and the routes that should be performed to serve a set of clients at minimum cost. The multi-trip variant considers the possibility for a vehicle to perform more than a single route during the planning period, and...

Modelling Laminate Failure in Composite Materials for Automotive Applications

David Moncayo, F. Köster, Pedro P Camanho, Daniel Coutellier, S. Hartmann

In order to capture the complexity of material failure it is necessary to understand that the performance of FE models depends on a fair use and a fair modeling of composite materials. Based on previous research works, the prognosis capabilities of the current material definitions in LS-DYNA will...

Exergy assessment of heat transfer inside a Beta type Stirling engine

Houda Hachem, Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah, Ibrahim Dincer

This paper presents an assessment of both energy and exergy efficiencies of a Beta Stirling engine prototype with a 30 W capacity as the maximum mechanical power output. Its operating pressure is close to atmospheric pressure, and it supports a maximum hot end temperature of 650 degrees C. The...

Use of the PIV and Electrochemical Techniques to Experimentally Characterize the Couette-Taylor- Poiseuille Flow Instabilities

Wafik Abassi, Fethi Aloui, Sassi Ben Nasrallah, Jack Legrand

The Taylor-Couette problem is a fundamental model in bifurcation theory and hydrodynamic stability. The inner cylinder rotation generates a flow pattern known by a transition to turbulence through a sequence of successive hydrodynamic instabilities. The effect of an imposed axial flow on the...

Advanced model based air path management using a discrete-angular controller in idle-speed context

Thomas Laurain, Jimmy Lauber, Reinaldo Martinez Palhares

This paper aims to present an original methodology to design a controller for the air path management considered as a nonlinear system that is presented as a periodic discrete Takagi-Sugeno (TS) model. A transformation is realized to translate the periodic behavior into a classic discrete model...
