18 Σεπ 2019 · A generalized methodology for evaluating the yield stress (𝜎 ′ p) of soils from cone penetration tests (CPT) is presented in terms of net cone resistance (q n e t = q t − 𝜎 v o) and material index, I c. The initial baseline expression is derived from a hybrid analytical solution combining spherical cavity expansion theory and critical ...
5 Απρ 2013 · The effective preconsolidation stress (Pc' = σ vmax ' = σp'), or yield stress (σy'), is defined as the point which separates elastic from plastic behavior. For coarser soils, including silts and sands that are difficult to both sample and test in this manner, in-situ tests may be valuable.
25 Φεβ 2013 · A generalized approach for first-order estimations of the effective yield stress (ωy' = preconsolidation stress) in a variety of soil types is developed for the cone penetration test (CPT).

26 Αυγ 2019 · The analysis of the experimental consolidation test data for undisturbed soils from the literature indicates that the log–log method yields conservative values of pre-consolidation stress.
1 Μαρ 2022 · We calculated Pollution Indices (PI) (Kowalska et al., 2018; Weissmannova and Pavlovsky, 2017) to assess the relative severity of soil contamination of heavy metals by anthropogenic sources using equation (1): (1) P I = C i C B where C i is the concentration of the ith metal in soil and C B is background soil concentrations as reported by the ...
6 ημέρες πριν · Soil compressibility was calculated as incremental strain per incremental stress, using stress in arithmetic scale. For a given sample, a local minimum in compressibility appeared close to the preload applied to the sample prior to the compression test. This yield stress is suggested as an expression of soil precompression stress.
