Elasticity and Strength of Materials Laboratory  - LERMA

The promotional actions of the LERMA laboratory have been of two types so far: the creation of a web space and spreading actions and contact establishments with other groups, nationwide and worldwide.
Creation of the web space
This web space has been created specifically for LERMA. The goal of this place is to show and spread LERMA's activity, and the possibilities that it offers to companies and institutions to collaborate in knowledge and technology transfer.

Contact establishment with groups
• We have contact and collaboration with Prof.T. Pekoz (Cornell University), in terms of stability under compression of open thin-wall sections, and of methodology of tests by means of buckling modes definition; with who we have made presentations together in work sessions.
• We have contacted with the metal racks research group of Trento University, who we have planned to organize together a seminar in Barcelona.
• We have established contact with the NEDCON-NL  Laboratory in Netherlands. We will work together on the testing of combined structures of racks.
• As part of the Reference in Advanced Techniques of Production Network (XARTAP), we have also started to be part of the EPM (Euroregion Pyrenees Mediterranean) Manufacturing.
• We are part of the workgroup of Fires and Explosions of the Public Security Institute of the Generalitat de Catalunya.
• We have established a collaboration relationship with IMAT. Technological Centre of Construction, for the mixed structures study.
Involvement in organizations
We have contacts with AEM-FEM. We usually collaborate together when it comes to racks, and more specifically, we organized together a seminar about rack's elements tests (ERF Workshop) during January of 2010 in Barcelona, at ETSEIB.

We have also taken part in TC7 (Technical Committee 7) WG 7.5 (Work Group 7.5) of the ECCS (European Convention for Constructional Steelwork), where we have taken part in several meetings. More specifically, we have collaborated in the organization of the last meeting that the group has had, which has been in Barcelona, at ETSECCPB, during January of 2010.
