This study presents a finite element model (FEM) to model temperature distribution for AISI H13 tool steel workpiece in electrical discharge machining (EDM) at different machining parameters (pulse current, pulse on-time, temperature-sensitive material properties, size of heat source, and material flushing efficiency). Scanning electron microscopy (SEM) with energy dispersive x-ray (EDX) and micro-hardness tests were used to validate accuracy of FEM predictions. Increasing pulse on-time leads to a higher depth of heat affected zone and increasing pulse current results in a slight decrease of depth of heat affected zone. There is a good agreement between experimental and numerical results.

Experimental investigation and 3D finite element prediction of the white layer thickness, heat affected zone, and surface roughness in EDM process Shabgard, Mohammadreza; Oliaei, Samad Nadimi Bavil; Seyedzavvar, Mirsadegh; Najadebrahimi, Ahmad (2011-12-01) An axisymmetric three-dimensional model or temperature distribution in the electrical discharge machining process has been developed using the finite element method to estimate the surface integrity characteristics of AISI H13 tool steel as workpiece. White layer thickness, depth of heat affected zone, and arithmetical mean roughness consisting of the studied surface integrity features on which the effect of process parameters, including pulse on-time and pulse current were investigated. Additionally, the e...
A crystal plasticity based finite element framework for RVE calculations of two-phase materials: Void nucleation in dual-phase steels Yalçınkaya, Tuncay; Çakmak, Serhat Onur (Elsevier BV, 2021-05-01) A crystal plasticity based finite element (CPFE) framework is developed for performing representative volume element (RVE) calculations on two-phase materials. The present paper investigates the mechanical response and the evolution of microstructure of dual-phase (DP) steels under uniaxial tensile loading, with a special focus on void nucleation. The spatial distribution and morphology of the ferrite and martensite grains in DP steels are explicitly accounted for by generating three-dimensional RVEs with V...
A numerical study on magneto-hydrodynamic mixed convection flow Bozkaya, Canan (2014-01-01) This paper, describes a study conducted to numerically investigate the two-dimensional, steady, laminar, magneto-hydrodynamic mixed convection flow and heat transfer characteristics in a lid-driven enclosure beneath an externally applied magnetic field. A solid square block is placed inside the cavity. The governing equations in the form of a stream function-vorticity-temperature formulation are solved numerically using the dual reciprocity boundary element method with constant elements. Treatment of nonlin...
A novel method to measure the glass and melting transitions of pharmaceutical powders Abiad, Mohamad G.; Gonzalez, David C.; Mert, Behiç; Campanella, Osvaldo H.; Carvajal, M. Teresa (Elsevier BV, 2010-08-30) A method to measure thermo-mechanical properties of pharmaceutical and polymeric powders was developed The measurements are conducted by characterizing the material's response to applied acoustic waves Measurements were performed using griseofulvin, felodipine and indomethacin as model drugs and polyethylene oxide (MW 200,000, 900,000, 2,000,000 Da) as model polymers. The method employed measures the mechanical Impedance enabled the calculation of the powder theological and thermo-mechanical properties. Mea...
A constitutive model for finite deformation of amorphous polymers FLEISCHHAUER, R.; Dal, Hüsnü; KALISKE, M.; SCHNEIDER, K. (2012-12-01) The paper introduces a three-dimensional constitutive model for the mechanical behavior of amorphous polymers, thermosets and thermoplastics. The approach is formulated in terms of finite deformations, appropriate for glassy polymers. The rheology of the model consists of a Langevin-type free energy function for the energy storage due to molecular alignment connected in parallel to a Maxwell element with a viscoplastic dashpot. The model proves successful for the constitutive description of glassy polymers ...
