    Poisson's ratio

    Hi, Thank you for all these answers.... :) BUT I think we didn't get it : we are dealing with common things, known by everyone studying mechanical properties of materials :) I'm looking for a Physical explanation of PR : why such a propety ? Okay, we can observe that a compressed material (in...

    Poisson's ratio

    Hello, I'm looking for informations about the poisson' ratio, deeper thant the basic definiton (ratio between transverse and longitudinal deformation). Where does such a property have its origin ? A fully amorphous material such as glass has a poisson' ratio around .3, as have a fully...

    Thermo-Mechanical Analysis

    Hello, I'm looking for informations on TMA and DTMA, especially about the measures that we can obtain with such a device. I'm looking for elastic constants on a PVC-based film. I've heard that DTMA could give me such properties, but I would like to have more informations on the phyisc behind...

    Looking for solids mechanics equations

    Hello, I'm currently looking for courses or other stuff on the Web on solids mechanics, such as the number of elasticiy constants needed for describing an orthotropic material... Thanks. Olivier

    Elastic Constants from PVC sheets

    Hello, I'm a R&D engineer currently working on PVC sheets, that have been obtained by extrusion. I have to find the elastics constants of this materials. As it is anisotrope due to the fabrication process, I would like to do two tensile tests in the sheet plane, and a compression test in the...
