Poisson's ratio (ν) = transverse strain / axial strain: ratio of shrinkage perpendicular to stress; typically 0.2-0.5.
Fórmula
Calculate Poisson\'s ratio: ν = (E-2G)/(2E)
- E
- E value — Variable used in the calculation
Guía paso a paso
- 1Input material properties: Young's modulus and shear modulus
- 2Calculate Poisson's ratio: ν = (E-2G)/(2E)
- 3Results show lateral deformation under load
Ejemplos resueltos
Entrada
Rubber: ν ≈ 0.5 (incompressible)
Resultado
Steel: ν ≈ 0.3 (some volume change)
Errores comunes a evitar
- ✕Confusing with strain/stress ratio
- ✕Not accounting for material nonlinearity
Preguntas frecuentes
Can Poisson's ratio exceed 0.5?
Theoretically no for isotropic materials (>0.5 = unphysical volume expansion).
