How is poisson's ratio calculated
WebPoisson's ratio μ P is related to the change of volume dV accompanying infinitesimal deformation d ε by the expression (31) for an incompressible material, ( dV / d ε) = 0 and μ P = 0.5. This value is the maximum possible value for any substance. WebThis is so Poisson’s ratio is determined within the elastic region of the material. When testing in accordance ASTM D638 for example, Poisson’s ratio is to be calculated …
