We present a novel physically-based method to visualize stress tensor fields. By incorporating photoelasticity into traditional raycasting and extending it with reflection and refraction, taking into account polarization, we obtain the virtual counterpart to traditional experimental polariscopes. This allows us to provide photoelastic analysis of stress tensor fields in arbitrary domains. In ou...

Simulation of model predictive control of casting mold temperature field is presented. Temperature fields of the mould have been modeled and studied using a finite element method based software package, ProCAST, and numerical models in the form of lumped-input/distributed-output systems have been obtained. For model predictive control synthesis the Model Predictive Control Toolbox was used. Sim...

The complicated physical phenomena which occur within solidifying metals during casting processes can not be easily observed. In the present paper the results of laboratory experiments with mould filling and freezing are presented. The experimental benchmarks have been constructed, based on so called analog fluids which are transparent and have well known physical properties: succinonitrile, po...

For a sample steel casting of cylindrical shape that was cast in metallic mould, the analysis influence and importance main boundary condition on simulation accuracy temperature field system casting-mould-environment performed. this system, frame bottom top casting, casting-mould interface analysed. As comparing quantity for accuracy, time-dependent (by means isotherms) mould total solidificati...

Pyroplastic deformation is a distortion of the ceramic shape during the sintering process. It occurs because the flow of the vitreous phase at high temperature and the applied stress due to the weight of the product during sintering process. The aim of this paper deals with describing a numerical-experimental method to evaluate the pyroplastic deformation, to predict the anisotropic shrinkage a...
