flexural rigidity The flexural rigidity of an elastic sheet is defined as ET3/12(1 − σ2) where E is Young's modulus, T is the thickness of the sheet, and σ isPoisson's ratio. In the Earth, the lithosphere is usually treated as an elastic sheet that responds to loading by ice-caps, volcanic piles, etc., from which the thickness of the lithosphere and the viscosity of the mantle can be derived.
