Webb5 sep. 2024 · 1. Introduction. Poisson's ratio (ν) is an important mechanical property for structural design (King, 1983), monitoring of ground deformation at active volcanoes (Manconi et al., 2007), and interpretation of in-situ seismic data (Hirn et al., 1991; Patane et al., 2002; Ji et al., 2009; Zaitsev et al., 2024a, Zaitsev et al., 2024b).For a solid material, ν … Webb11 feb. 2024 · In the limit of Poisson ratio of 0.5, the material behavior becomes incompressible. Real solids exhibit Poisson ratios <0.5. For a fluid under static conditions, it is possible to define a Poisson ratio in terms of the equation of state for the fluid.
