WebJan 1, 2024 · Thus, PDMS with 10:3 (w/w) mixing ratio presented the highest Young’s modulus. Regarding hardness, the values found for PDMS with mixing ratios 10:1 and 10:2 were 41.7±0.948 and 43.2±1.032 Shore A were close to the one declared by the manufacturer, 44 Shore A, when using 10:1 as mixing ratio. WebPoisson's ratio. The Poisson's ratio is the ratio of the relative strain contraction (or transverse strain) normal to the applied load - to the relative extension strain (or axial stress) in the direction of the applied load. The Poisson's coefficient can be expressed as: μ = - et / el (1) where.
