"WebbHere, the negative Poisson ratio suggests that the material will exhibit a positive strain in the transverse direction, even though the longitudinal strain is positive as well. For most materials, the value of Poisson’s ratio lies in the range, 0 to 0.5. A few examples of poisson’s ratio are given below for different materials. " - The poisson ratio of palladium thin film

WebbIt is known that a quite repeatable way of generating excess heat in the electrolysis Pd/D system is the co-deposition technique (S. Szpak, P.A. Mosier-Boss and J. J. Smith, J. Electroanal. Chem., 302 (1991) 255.). One advantage is that a higher D/Pd ratio is relatively easy to achieve with co-deposition compared to ordinary electrolysis methods. However, … Webb19 mars 2024 · Poisson’s ratio, ν, is defined as ν = -lateral strain/longitudinal strain. It is applied when analyzing the lateral strain on members subjected to axial forces (compression and tension). None of the beams in the diagrams of your link involve axial loading (loads applied to the ends of the beams along the axis of the beam).
