AGATA SLIWA, MAREK SROKA, KATARZYNA BLOCH, IOAN GABRIEL SANDU, MOHD MUSTAFA AL BAKRI ABDULLAH, ANDREI VICTOR SANDU FINITE ELEMENT METHOD APPLICATION FOR THE DETERMINATION OF HARDNESS FOR MAGNESIUM ALLOYS A numerical model was made to establish the casting hardness for the magnesium alloys MCMgAl12Zn1, MCMgAl6Zn1, MCMgAl3Zn1 and MCMgAl9Zn1. Computer simulation of hardness was performed using the finite element method in ANSYS environment, and the hardness values were obtained by experiments based on the Rockwell method. The showed model fulfils the initial criteria, which provides with the basis for the assumption about its utility in establishing the casting hardness of the magnesium alloys MCMgAl12Zn1, MCMgAl6Zn1, MCMgAl3Zn1 and MCMgAl9Zn., using the finite element method within the framework of the ANSYS program. There is the correlation of the computer simulation results with the experimental outcomes. Nowadays the computer simulation is very well known, and it is based on the finite element method, what it makes possible to better comprehend the autonomy between the process parameters and selected optimal solution. The chance of applying faster and faster calculation machines and the formation of much software enables creating the more accurate models and more the adequate ones to reality.
