<title>ABSTRACT</title> <p>Rubber is the main element of tires and outside layer tracks. Tire track heating caused by hysteresis effects due to deformation rubber during operation. temperatures can depend on many factors, including tire geometry, inflation pressure, vehicle load speed, road type temperature environmental conditions. The focus this study develop a finite approach computationally evaluate field steady-state rolling track. 3D thermal analysis software Radtherm...
A three-dimensional finite element model was developed to predict the temperature distribution and phase transformation in deposited stainless steel 410 (SS410) during Laser Engineered Net Shaping (LENS™) rapid fabrication process. The development of carried out using SYSWELD software package. calculates evolution part a SS410 plate. metallurgical transformations are taken into account temperature-dependent material properties continuous cooling diagram. ferritic martensitic as well...
Several aspects of the thermal behavior deposited stainless steel 410 (SS410) during laser engineered net shaping (LENS™) process were investigated experimentally and numerically. Thermal images in molten pool surrounding area recorded using a two-wavelength imaging pyrometer system, analyzed THERMAVIZ™ software to obtain temperature distribution. The size, gradient, cooling rate obtained from history profiles. dynamic shape pool, including size both travel direction depth was investigated,...
Understanding the columnar to equiaxed transition (CET) is vital in production of materials with superior properties using casting, welding, and additive manufacturing processes. In this study, a three dimensional (3D) phase field-lattice Boltzmann (PF-LB) model was developed simulate CET directional solidification Inconel 718 alloy. The field (PF) method used determine solid/liquid transition. solute diffusion equation solved by lattice (LBM), due its suitability for parallel processing...
Abstract A finite element model capable of simulating solidification binary alloys and the formation freckles is presented. It uses a single system equations to deal with all-liquid region, dendritic all-solid region. The region treated as an anisotropic porous medium. algorithm bilinear isoparametric element, penalty function approximation Petrov-Galerldn formulation. Numerical simulations are shown in which NH4Cl-H2O mixture Pb-Sn alloy melt cooled. process followed time. Instabilities can...
