2 Ιαν 2024 · Effective vertical yield stress (σ′ xy) is essential in accurately describing fine-grained soils’ mechanical properties and their behaviour under load over time. It helps assess settlements and...
1 Ιουν 2018 · Here thought, the yield stress ratio ( YSR ) is used to determine the value of preconsolidation stress resulting from mechanical overburden than can be changed by many post depositional...
9.5.1 Effective Yield Stress from Cone-Penetration Tests For uncemented and low-sensitivity soils composed of basic minerals (e.g., quartz, kaolin, illite), the effective yield stress is related to the net cone resistance (Figure 9-9) and is given by the following expression (Mayne et al. 2009): = 0.33 ( 100â ) The exponent depends upon the ...
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.
25 Φεβ 2013 · A generalized methodology for evaluating the yield stress (σ 0 p) of soils from cone penetration tests (CPT) is presented in terms of net cone resistance (q net ¼ q t − σ vo) and material ...
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.
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.
