In this paper, the development and application of a new upper bound limit method for two- three-dimensional (2D 3D) slope stability problems is presented. Rigid finite elements are used to construct kinematically admissible velocity field. Kinematically discontinuities permitted occur at all inter-element boundaries. The proposed formulates problem as an optimization based on theorem. objective function determination minimum value factor safety has number unknowns that subject set linear...
Abstract Clay minerals are non-spherical nano-particles interacting through ranged van der Waals forces. Discrete Element Simulations usually use coarse numerical integration based on sphere clusters, as available analytical formalisms limited. In this paper, we discuss the implementation of a force for cuboid particles derived in previous research. particular, describe some corrections necessary its extension to pairs finite-sized particles.
As label-free biomarkers, biophysical properties of cells are widely used for cell type classification. However, intrinsic markers, e.g., specific membrane capacitance (Cspecific membrane), cytoplasm conductivity (σconductivity) and instantaneous Young's modulus (Einstantaneous) measured hundreds single were not yet reported. In this study, in suspension (adherent treated with trypsin) aspirated through a microfluidic constriction channel at 25 °C, the entry processes impedance profiles...
To give engineers involved in planning and designing of asphalt pavements a more accurate prediction crack initiation propagation, theory-based models need to be developed connect the loading conditions fracture mechanisms present laboratory tests under traffic loading. The aim this study is develop technical basis for simulation behavior pavements. cohesive zone model (CZM) approach was applied commercial FE software ABAQUS analyze propagation layers. CZM from mixtures can used simulate...
In this paper, a continuous feedback tracking controller is developed for class of high-order multi-input multi-output (MIMO) nonlinear systems with an input gain matrix that has nonzero leading principal minors but can be nonsymmetric. Under the mild assumption signs control are known, yields locally uniformly ultimately bounded (UUB) while compensating unstructured uncertainty in both drift vector and matrix. First, full-state designed based on limited assumptions structure system...
Uncertainty is a notable feature of the geotechnical field. Reliability analysis methods provide more rational solution than deterministic ones in presence spatial variability soil properties. Two types reliability were employed face stability pressurized tunnels this study: random variable method (RVM), which ignores autocorrelation parameters, and finite-difference (RFDM), considers autocorrelation. In RVM, first-order second-moment (FOSM) was adopted to calculate index with less...
Summary Large‐scale engineering computing using the discontinuous deformation analysis (DDA) method is time‐consuming, which hinders application of DDA method. The simulation result a typical numerical example indicates that linear equation solver key factor affects efficiency In this paper, highly efficient algorithms for solving equations are investigated, and two modifications programme presented. first modification with high efficiency. block Jacobi (BJ) iterative conjugate gradient...
This paper develops a hybrid Bayesian copula model for the reliability analysis of an operational metro tunnel in dependent system which risk factors interact with each other. The method used present studies demonstrates two major deficiencies. First, failure criteria structural systems, cannot describe complex interactions among these criteria, are considered independent one another. Second, traditional is typically confined to static process reasoning, reflect time-varying effects adjacent...
