Behaviour factors of MR steel frames with semi-rigid connections: a parametric study

In this paper same results are presented, related to the parametric study of the q-factor of steel moment resistant frames. The study considers semi-rigid beam-to-column joints with standard behaviour, characterized by their stiffness, resistance and deformation capacity. Three performance levels or limit states are considered, Serviceability Limit State (SLS), Damageability Limit State (DLS) and Ultimate Limit State (ULS)

Overview of the mean of production used for FSW

The Friction Stir welding process is now introduced in production plants. More and more applications are developed and the most part of the work is now centered on the mean of production to be used. Institut de Soudure and Arts et Métiers ParisTech are working on this subject since mid of 2005. The results of this work is a recognize knowledge on the methodology for qualifying a Friction Stir Welding Equipment [1]. In the same time, and based on this work, Institut de Soudure has bought a new kind of Friction Stir Welding machine based on a KUKA Robot

On the propagation of plane waves in piezoelectromagnetic monoclinic crystals

In a piezoelectromagnetic crystalline medium belonging to the class 2 of the monoclinic crystallographic system we find some classes of piezoelectricity-induced electromagnetic waves. These are time harmonic plane waves propagating along the symmetry axis and depending only on the axial coordinate. There are two indepen- dent modes of propagation, one longitudinal and one transverse, with mechanical and electromagnetical couplings. The transverse mode admits as a particular case an electromagnetic wave with no associated elastic deformation

The CIMNE model for generating knowledge on computational engineering and its transfer to society

We present an overview of the model implemented by the International Centre for Numerical Methods in Engineering (CIMNE, www.cimne.com ) for the generation of scientific and technical knowledge on computational engineering, understood in the broad sense, the subsequent generation of product resulting from the research activities and the transfer of these products to society for their exploitation in the industrial sector. We present examples of application of the CIMNE model to a number of academic, scientific and industry activities of CIMNE .Preprin

Tribute to Krzysztof Wilmanski

Some 20 years ago, Krzysztof Wilmanski began his research into the theory of porous and granular media, fields that are addressed in this special issue of Acta Mechanica. In contrast to earlier models for such media, Wilmanski introduced the porosity as a material field, and he derived a particular balance equation for this quantity based on thermodynamic arguments. A principal application of the resulting continuum model has been the investigation of linear wave propagation. This was the topic of one minisymposium at the 8th European Solid Mechanics Conference in the Graz University of Technology, Austria, 9–13 July 2012
