Dynamic pull‐in behavior of nonlocal functionally graded nano‐actuators by considering Casimir attraction is investigated in this paper. It assumed that the nano‐bridge initially at rest and fundamental frequency nano‐structure as a function system parameters obtained asymptotically Iteration Perturbation Method (IPM). The effects actuation voltage, parameter, properties FGM materials intermolecular force on dynamic are studied. exhibited two terms series expansions adequate to achieve...
AbstractIn the present study, an optimization approach based on firefly algorithm (FA) is combined with a finite element simulation method (FEM) to determine optimum design of pump and treat remediation systems. Three multi-objective functions in which pumping rate clean-up time are variables considered proposed FA-FEM model used minimize operating costs, total volumes rates three scenarios while meeting water quality requirements. The groundwater lift contaminant concentration also...
SUMMARY One major difficulty in seepage analyses is finding the position of phreatic surface which unknown at beginning solution and must be determined an iterative process. The objective present study to develop a novel non‐boundary‐fitted mesh finite‐element method capable solving unconfined problem domains with arbitrary geometry continuously varied permeability. A new finite element named as smoothed fixed grid (SFGFEM) used simplify variable domain seepage. gradient smoothing technique,...
This paper presents the high order frequency-amplitude relationship for nonlinear transversely vibrating beams with odd and even nonlinearities, using Homotopy Perturbation Method an auxiliary term (HPMAT). The governing equations of buckled beam, beam carrying intermediate lumped mass, quintic are investigated to exhibit reliability ability proposed asymptotic approach. It is demonstrated that two terms in series expansions sufficient obtain a highly accurate periodic solutions. integrity...
