Controlling role of suction stress in the Atterberg limits
Soil plasticity and consistency are indicators of a soil’s strength and deformation as a function of water content. They are often treated as secondary concepts in geotechnical analysis, likely due to the arbitrary and empirical nature of their definitions—such as those associated with plastic and …

Confiabilidade de estruturas reticuladas em ambientes de processamento paralelo
… probability of framed structures. A elast-plastic limit state function to structural elements and specialists methods were used for this purpose. A method to identify the most likely failure modes was developed. The software was implemented in a parallel computer with a host (microVax) …

Probabilistic analysis of the plastic collapse of random media
… the reliability of an elastic/perfectly plastic continuous medium exhibiting randomly varying yield strength. Both the Tresca and Mohr-Coulomb yield criteria are considered in the present study. The two probabilistic methods developed are based on the upper and lower bound theorems of …

Elementos finitos para a análise limite de cascas axissimétricas via programação não-linear
This work is concerned with rigid-plastic limit analysis of shells of revolution subject to rotationally symmetric loadings. These shells, of arbitrary shape, are discretized into a series of finite elements, each being a conical shell. The von Mises condition, valid for sandwich shells, is used. …

Towards a unified design-by-analysis solution to pressure vessel nozzle-shell junctions under combined loading
… stress linearization, external loading cases, limit loads, and cyclic loads. In addition, elastic, elastic - perfectly plastic, full plastic and fracture analysis were performed.Stress intensity factors are obtained with the results of finite element analysis for various internal pressure and …

Effects of Mica On Soil Properties For Embankment Construction
… gravity, particle size distribution, liquid limit, plastic limit, and soil classification. Tests for mechanical properties include standard Proctor compaction, direct shear, and triaxial compression. Tests for chemical properties include soil pH, soil resistivity, chloride content and sulfate …

Foundation Design of Low Volume Roads: Evaluation and Performance
… testing included moisture content, liquid limit, plastic limit, and gradation tests. The results of the tests were used to compare the layer thicknesses and material properties to both the performance of the roads and the suggested thicknesses and material specifications from the SDDOT …

Saturated–Unsaturated behaviour of compacted clays
… a moderate water adsorption capacity (liquid limit of 29% and plastic limit of 15%) was characterized to provide baseline geotechnical properties. This material was classified as lean clay according to the Unified Soil Classification System. Field behavior was simulated using regional climatic …

Lime treatment to improve frictional resistance and stability of stiff clay slopes
… particle size, shape and arrangement, Atterberg plastic limit and liquid limit as indirect measures of changes in particle size and shape, and fully softened friction angle and residual friction angle, are used to examine possible mechanisms of lime-soil reactions. The main variables, in addition …

Distribution and dispersion of metals and their economic potential: a case of the Fumani Tailings Dam, Limpopo Province, South Africa
… dams. The Major oxides, sieve analysis, liquid limit test and the plastic limit test were used to classify the tailings using USCS and AASHTO Classification system. The USCS revealed that the tailings were ML and/or CL fine grained silty clay, whilst AASHTO Classification system revealed that …

Mitigating risk of weather variability to agriculture through improved field workability predictions
… By standardizing volumetric soil moisture by the plastic limit (PL) or field capacity (FC) different soils are taken to have the same thresholds for workability. I compared different models for determining the thresholds for field workability. As a validation dataset, 97 estimated soil moisture …

Developing a system to measure rheology of conditioned soil for soft-ground TBM tunneling
… rheology of conditioned soil. The Bingham plastic model is shown to be a suitable model to represent the rheology of conditioned soil. The operational range of the system’s rotational speed for this purpose is between 3 rpm and 60 rpm. Furthermore, a parametric study using CFD modeling was …
