In this study, a nonlinear structural model is developed to simulate the cyclic axial force-deformation behavior of steel braces including their buckling behavior using the commercially available nonlinear finite element based software ADINA. The nonlinear cyclic axial force-deformation simulation is done for braces with box sections. However, the structural model and simulation techniques described in this study may be applicable to braces with various section types using other commercially available structural analysis software capable of handling material and geometric nonlinearity. The developed nonlinear brace model is verified using available test results from the literature. It is found that the accuracy of the shapes of the analytical hysteresis loops and the energy dissipated compared to the experimental ones is satisfactory for analysis and design purposes in practice. The developed nonlinear brace structural model is then used to study the effect of various ground motion and structural parameters on the seismic response of single story, single bay concentrically braced frames with chevron braces.

Modelling and Monte Carlo simulation of the atomic ordering processes in Ni3Al intermetallics Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (IOP Publishing, 2007-03-01) The evolution of atomic ordering processes in Ni3Al has been modelled by a Monte Carlo ( MC) simulation method combined with the electronic theory of alloys in pseudopotential approximation. The magnitudes of atomic ordering energies of atomic pairs in the Ni3Al system have been calculated by means of electronic theory in pseudopotential approximation up to the 4th coordination spheres and subsequently used as input data for MC simulation for more detailed analysis for the first time. The Bragg - Williams l...
Numerical simulation of solidification kinetics in A356/SiCp composites for assessment of as-cast particle distribution CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2009-06-01) The present work is aimed at studying the effect of solidification rate on reinforcement clustering in particle reinforced metal matrix composites (PMMCs) through numerical simulations and experimental studies. A macrotransport-solidification kinetics (MTSK) model was used to simulate the solidification kinetics of the PMMCs. The experimental validation of the numerical model was achieved through the Newtonian and Fourier thermal analysis methods. Results reveal that the MTSK model can be successfully used ...
Investigation of effect of design and operating parameters on acoustophoretic particle separation via 3D device-level simulations Sahin, Mehmet Akif; ÇETİN, BARBAROS; Özer, Mehmet Bülent (Springer Science and Business Media LLC, 2019-12-16) In the present study, a 3D device-level numerical model is implemented via finite element method to assess the effects of design and operating parameters on the separation performance of a microscale acoustofluidic device. Elastodynamic equations together with electromechanical coupling at the piezoelectric actuators for the stress field within the solid parts, Helmholtz equation for the acoustic field within fluid, and Navier-Stokes equations for the fluid flow are coupled for the simulations. Once the zer...
Modeling of the nonlinear behavior of steel framed structures with semi rigid connections Sarıtaş, Afşin; Özel, Halil Fırat (null; 2015-07-21) A mixed formulation frame finite element with internal semi-rigid connections is presented for the nonlinear analysis of steel structures. Proposed element provides accurate responses for spread of inelasticity along element length by monitoring the nonlinear responses of several crosssections, where spread of inelasticity over each section is captured with fiber discretization. Each material point on the section considers inelastic coupling between normal stress and shear stress. The formulation of the ele...
Investigation of Mechanical Properties and the Electronic and Magnetic Behavior of Silver-Based Ferrite Chalcogenides Ag3FeCh4 (Ch = S and Se). Sürücü, Gökhan (2020-09-01) In this study, to obtain the mechanical properties and the electronic and magnetic behavior of silver-based ferrite chalcogenides Ag3FeCh4 (Ch = S and Se), first principles computations within generalized gradient approximation have been performed. They conform P4 ̅3m space group with 215 space number which have sulvanite type simple cubic structure. At the beginning, in order to determine most suitable magnetic order, A, C and G type antiferromagnetic (AFM) and ferromagnetic (FM) phases have been considere...
