(9), which depends on the thermodynamic pressure given by Eq. (55) P T = P 0 + ∑ α ϕ α Δ u α = u A + ∑ ϕ α ( u α − u A). By rearranging the last equation we can always (formerly) express PT in a Bishop form with χ = ϕ W + ϕ S ( u A − u S) / ( u A − u W). dolphins harassed in hawaii

Effective Stress Principle for Partially Saturated Rock Fractures

Webb15 aug. 2014 · Bishop (1959) considered the case of contacts between the particles with non-zero spatial dimensions, illustrated on the left side of Fig. 1 ... (1997) concluded on that basis that at higher stresses significant deviations from Terzaghi's effective stress principle occur. WebbA definition of effective stress in partly saturated soils has been proposed by Bishop (1959) (see also Bishop, Alpan, Blight and Donald, 1960). σ' = σ - u a + χ (u a - u w) (3.8) where χ is a parameter which may vary from 0 to 1. When χ = 1 the soil is saturated and equation (3.8) simplifies to σ' = σ - u w (3.6)
