Božidar BRUDAR

Dr. Božidar Brudar has devoted most of his career to research work in the industry. He has mostly been interested in innovations and the mathematical modeling of technological processes in metallurgy. He had a major success in constructing a measuring device for the optimal cutting of hot steel blooms in the rolling mill of Jesenice Steel Works. In mathematical modeling of processes in metallurgy, he has focused on the problems of the optimal heating of steel blocks and the solidification of steel in molds. Later on, he shifted his research interest to nondestructive methods using electromagnetic fields. He introduced mathematical methods for the calculation of electromagnetic fields in the vicinity of defects in ferromagnetic materials. He is looking at the limitations of several methods in discovering defects in materials. He is also active in mathematical statistics in the planning of the necessary number of measurements. He has drawn attention to mistakes in the research results when the principles of testing hypotheses are not taken into account.
