Electromagnetic-thermal coupled numerical analysis of induction heating is time intensive if three-dimensional models are used. In this study, by processing the results of finite element computations, a dimensional analysis is carried out to predict the transient temperature rise time at the surface of an induction heated workpiece. A unique set of curves is found that describes the transient dimensionless temperature at a point on the surface as a function of the electromagnetic skin depth alone. The effectiveness of the approach is verified by numerical calculations and comparing the dimensionless temperature curves for different heating cases and materials. Effect of temperature dependent thermal properties is also investigated. The consistency of numerical results is also verified by comparison with experiments.

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 ...
Sheet metal forming analyses with an emphasis on the springback deformation FIRAT, MEHMET; Kaftanoglu, Bilgin; Eser, Orhan (Elsevier BV, 2008-01-21) An accurate modeling of the sheet metal deformations including the springback is one of the key factors in the efficient utilization of FE process simulation in the industrial setting. In this paper, a rate-independent anisotropic plasticity model accounting the Bauschinger effect is presented and applied in the FE forming and springback analyses. The proposed model uses the Hill's quadratic yield function in the description of the anisotropic yield loci of planar and transversely anisotropic sheets. The ma...
Control of the thickness distribution of evaporated functional electroceramic NTC thermistor thin films Schmidt, R.; Parlak, Mehmet; Brinkman, Am (Elsevier BV, 2008-04-01) In this work the thickness distribution of NTC thermistor thin films produced by low deposition rate (0.8 nm s(-1)) electron-beam evaporation is investigated. The target preparation, deposition conditions and geometrical set-up of the evaporation mechanism are described in detail. The evaporation geometry is shown to be critical for the thickness distribution of evaporated films. The film thickness distribution of evaporated layers was measured across a macroscopic film surface using Alpha Step stylus profi...
APPLICATION OF 3 NONLINEAR-PROGRAMMING TECHNIQUES IN OPTIMIZING MACHINING CONDITIONS ESKICIOGLU, AM; ESKICIOGLU, H (SAGE Publications, 1992-01-01) Mathematical models used for determining optimal machining conditions are non-linear functions subject to non-linear constraints. In this paper models for unit production cost and unit production time for multi-pass milling operations are developed, taking cutting speed, depth of cut, feed and number of passes as design variables. The problem is then solved by three non-linear programming methods, namely the generalized reduced gradient (GRG) method, the sequential unconstrained minimization technique (SUMT...
Effect of solidification rate on spatial distribution of SiC particles in A356 alloy composites CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2008-08-26) The damage and deformation behaviour of particulate reinforced metal matrix composites (PMMCs) can be highly sensitive to local variations in spatial distribution of reinforcement particles, which markedly depend on melt processing and solidification stages during production of PMMCs. The present paper attempts to study the effect of solidification rate on cluster formation in an Al-Si-Mg (A356) alloy composite reinforced with SiC particles and to explore the applicability of spatial functions to PMMC micro...
