Note: Exceptions to the typical values given above often occur. High fines contents and/or high moisture contents tend to reduce Young's modulus and increase Poisson's ratio. Unusually low fines contents and/or low moisture contents have the opposite effect. Poisson's ratio for a completely saturated material will be close to 0.50.
