Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

The theoretical basis of classic geotechnical engineering stability problems is limit analyis thereom. Incremental loading finite elements and strength reduction finite elements were put forward by Zienkiewicz in 1975 and the methods are called by the authors Limit Analysis Finite Elements (abbreviation LAFE for short). It has been successfully applied to slope engineering, and used to bearing ...

In order to strengthen disaster prevention control under deep resource development and space utilization, it is necessary construct a damage intrinsic model complex stress states predict the mechanical behavior of deep-rock mass cyclic loading. An indoor uniaxial loading test on sandstone was carried out in this paper. By analyzing properties energy transformation failure process, assumed that ...

We present a two-dimensional analytical solution for the static stress field around rough interlocked interface under background stresses and its applications to faulting. The is derived using perturbation theory defined topography stresses. failure-ratio, which scales likelihood failure of bulk material interface, calculated adopting Coulomb criterion. compare model predictions with results ex...

This study aimed to analyze the defects of large residual stress in laser additive manufacturing metal parts by establishing a milling numerical simulation Ti6Al4V titanium alloy thin-walled based on Johnson-Cook constitutive model alloy, modified Coulomb friction model, physical chip separation criterion and other theories, combined with finite element software ABAQUS. The influences depth, in...

quadratic stark constants of neutral copper spectral lines for all s,p, and d levels are calculated using the coulomb approximation. these results are compared with existing data and, generally, good agreement is observed

We give a potential-theoretic characterization of measures μ0 which have the property that Coulomb gas, defined with respect to prior μ0, is “well-behaved” and similarly for more general Riesz gases. This means laws empirical corresponding random point process satisfy Large Deviation Principle rate functional depends continuously on temperature, in sense Gamma-convergence. Equivalently, there n...
