Finite element modeling of micro particle separation using ultrasonic standing waves
Süleyman, Büyükkoçak; Çetin, Barbaros; Özer, Mehmet Bülent (2014-08-07)
Acoustophoresis which means separation of particles and cells using acoustic waves is becoming an intensive research subject. The method is based on inducing an ultrasonic compression standing wave inside a microchannel. A finite element approach is used to model the acoustic and electro-mechanical behavior of the piezoelectric material, the micro-channel geometry as well as the fluid inside the channel. The choices of silicon and PDMS materials are investigated as the chip materials for the resonator. A se...
Finite element modelling and analysis of recoil springs in automatic weapons
Zaloğlu, Hakan; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2013)
As a tool for weapon designers, a finite element based analysis methodology is developed for estimating the mechanical behavior of the recoil spring during a firing cycle. All models are developed in LS-DYNA to be used in analysis to estimate the nonlinear force deflection characteristics and dynamic stress in the spring during a representative firing cycle. An experimental study is also performed to validate the finite element based analysis methodology. Modeling, analysis approach and modeling parameters ...
Finite element analysis of shearing processes
Isbir, S.; Darendeliler, Haluk; Gökler, Mustafa İlhan (null; 2006-12-01)
Shearing of sheet metal is extensively used in manufacturing industry. It is a highly non-linear process and involves complex mechanisms such as crack initiation and propagation, and deliberate fracture of the material for obtaining the desired geometry. Finite element method can be used for the design of shearing process. However, most of the general purpose commercial finite element analysis programs do not provide ready-to-use facilities to simulate shearing. In this paper, finite element simulation of s...
