Laboratory for Simulation of Materials and Processes

Laboratory for Simulation of Materials and Processes


Head: Prof. Božidar Šarler

 

Deputy Head:  dr. Boštjan Mavrič

 

  Activities 

A principal activity of the laboratory, established at the beginning of 2013, is development of topmost basic science for numerical modelling of materials and processes and use of this knowledge in improvement of production processes and products. The vision is to maintain the achieved leading role in the development of numerical methods and modelling of multiphase systems at different scales and to help Slovenian and global industry in establishing a world-class technological processes and products in the most economical and environmentally friendly way.

The fundamental research efforts are focused on contributing to the world treasury of knowledge with new approaches of modeling liquid-solid and solid-solid systems, with new meshless numerical approaches for modeling problems with moving boundaries and with laboratory and industrial test cases and reference calculation of solidification problems. We are particularly focused on the simulation of coupled transport phenomena and electromagnetic fields.

The applied research is focused on establishment of all the elements for through process of modeling for the aluminum and steel industry, especially for the various processes of casting, rolling and heat treatment. The ultimate goal is the modeling of product characteristics as a function of process paremeters of each of the process steps. This is achieved by the coupled physical models of relations between the process variables, microstructure and properties of the product. The physical modeling of microstructure evolution is supplemented, replaced or calibrated, based on the artificial intelligence methods. The manufacturing processes are optimized based on minimization of various object functions: eg. macroscopic, which take into account factors such as the productivity of the process and use of energy and raw materials, and such as microscopic, which take into account the characteristics of the product as a function of microstructure.
