Paper Abstract

New we propose a simple method of determination of Poisson's ratio for auxetic materials like the polyamide foams. These measurements were performed for the conventional materials and also auxetic foams. This method is based on a diffraction pattern observation using CCD camera connected to PC computer. The diffraction pattern are used for real-time monitoring of the foam diameters and their extension due to streach.
