...Vedanth Srinivasan; De Ming Wang; David Greif; Maik Suffa In this paper, we present the results of the numerical computations carried out to simulate the direct immersion quenching process of several test pieces such as (1) trapezoidal block, (2) hollow block, and (3) engine-cylinder head using...

...András Roósz; Gábor Karacs The aim of the simulation was to calculate the austenitization processes in plain carbon steels with different carbon concentrations. As the first step of simulation, an initial structure was generated where the diameters of pearlite colonies, the thickness...

... system was solved with the numerical code RADAU5. Computed and measured reaction forces and moments agreed well within the accuracy of the measurements. The calculated joint loads are consistent with results from the literature. The forward dynamics model can be used to simulate consecutive ski turns...

...). The mathematical model is based on the solution of the coupled transient heat, momentum, and solute transport equations, under laminar or turbulent flow conditions, during the remelting and cooling of a cylindrical ingot. An important part of the overall work is the careful validation of numerical simulations...

...Y. Huang; W. Zhan; B. Fritz; S. Thomson; A. Fang The drift of aerially applied crop protection and production materials is studied using a novel simulation-based design of experiments approach. Many factors that can potentially contribute to downwind deposition from aerial spray application...

...V. A. Pozdnyakov; O. V. Borisov; V. P. Filippova A new method of simulation of residual stresses in ribbons of amorphous metallic alloys is proposed. The model considers the total deformation remaining in an amorphous metallic alloy during the quenching from liquid state to be the sum of elastic...

.... The main reason is that no standard sample exists with known cleanliness properties. To solve this problem, we have developed a simulation approach. In this case, the different methods of cleanliness assessment are simulated on virtual samples. The inclusion populations are perfectly known in this kind...

.... Currently used simulation models, including the most widely accepted models, such as the effective heat capacity method and the enthalpy method, come short when handling phase change processes that start from partially melted states. The characteristics of how the heat is absorbed or released during...

...Huiping Li; Guoqun Zhao; Lianfang He Mathematical models of computing carbon content are given in this paper. To improve the computation accuracy of carbon content, lumped parameters and mesh refinement are used in the simulation process. Finite element method (FEM) software for simulating carbon...

...Caner Şimşir; C. Hakan Gür Modeling and simulation of quenching are powerful tools in the design, optimization, and understanding of the quenching process since they provide quantitative results such as the evolution of microstructure and the internal stresses, which are practically impossible...

...Martin Mössner; Dieter Heinrich; Peter Kaps; Herwig Schretter; Werner Nachbauer A computer model was developed to simulate consecutive ski turns. The model consists of a segment model for two skis and a single body for the skier. It was implemented in the multibody simulation software LMS...

...RN Penha; LCF Canale; GE Totten; GS Sarmiento; JM Ventura This paper describes the use of computational simulation of heat transfer and resulting residual stress obtained by quenching a standard probe into different quench oils. Cooling curves were obtained after immersing a preheated 12.-mm...
