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 ...

RESUMO The permanence of a plant species in forest community depends on its number specimens and distribution the various sizes individuals, including seedlings. Seedlings seeds from remnant Pirassununga were collected analyzed for degree threat, possible height adult individual, occurrence phytophysiognomies region morphological aspects. 116 seedlings available 39 morphospecies collected, germ...

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
