Webbspectroscopy. Measuring the Poisson’s ratio of a coating is extremely difficult and for this reason it is often assumed that the Poisson’s ratio of a coating is the same as that of the bulk material. However, this is often not the case. A method is therefore proposed by which the Poisson ratio, ν, can be determined by comparing the 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 … diary writing for class 6
