In this study buckling analysis of solid rectangular plate made of porous material bounded with the layers of piezoelectric actuators in undrained condition is investigated. Porous material properties vary through the thickness of plate with a specific function. Distributing of the pores through the plate thickness is assumed to be the nonlinear nonsymmetric distribution. The ...

Analyzing piles subjected to lateral loads significantly depends on soil resistance at any point along the pile as a function of pile deflection, known as p-y curve. On the other hand, the deformation characteristics of soil defined as “the soil strain at 50% of maximum deviatoric stress (ε50)” has considerable effect on the generated p-y curve. In this research, several models are proposed to ...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

Borehole tube sampling is a key process of geotechnical engineering. The paper presents numerical analyses smooth in clay using the particle finite-element method. soil described by conventional elasto-plastic constitutive model (Tresca plasticity and quasi-incompressible elastic law). sampler advanced several diameters into until steady state observed. solution for round-tipped clearly identif...

Tile drainage belongs to one of the most important meliorative measures in Czech Republic. It has been hypothesised that it may improve some soil properties which are influenced by groundwater and their water regime. In case meadows, used management method also influence properties. this study, different physical (particle bulk density, total porosity, maximum capillary capacity, minimum air re...
