The study presents the investigation of elastic behavior soil in optimal design continuous foundations according to rigid solid case. For investigation, optimization algorithm that can find section and reinforcement details has been developed. developed uses one well-known meta-heuristic methods named artificial Bee Colony method design. Winkler spring hypothesis (analytic solution) is used cal...

In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...

Studies have shown that the pore seepage in soft clay deviates from Darcy's law, with compressibility and permeability of soil demonstrating obvious nonlinear characteristics during consolidation process. These factors will affect sand drain foundation In order to explore mechanism saturated clay, this paper introduces UH model considering time effect describe deformation relation skeleton unde...

In this paper, a novel technique is presented to solve tolerance design problems. To achieve the desired performance tolerance, the technique uses a subtle, but significant, change in the design: the addition of a tuning parameter in place of an increase in component precision. Statistical models are used to develop a framework for the tuning parameter design method. Also developed is a new, di...

Based on the theories of thermal elasticity mechanics and nonlocal elasticity, an elastic Bernoulli–Euler beam model is developed for thermal-mechanical vibration and buckling instability of a single-walled carbon nanotube (SWCNT) conveying fluid and resting on an elastic medium. The finite element method is adopted to obtain the numerical solutions to the model. The effects of temperature chan...
