Finite Element Method application for modelling of mechanical properties

Purpose: A numerical model was developed in order to predict the hardness for casting the magnesium alloys MCMgAl12Zn1, MCMgAl6Zn1, MCMgAl3Zn1 and MCMgAl9Zn1.Design/methodology/approach: Computer simulation of hardness was carried out with the help of finite element method in ANSYS environment, and the experimental values of hardness were determined basing on the Rockwell method.Findings: The presented model meets the initial criteria, which gives ground to the assumption about its usability for determining the hardness in casting the magnesium alloys MCMgAl12Zn1, MCMgAl6Zn1, MCMgAl3Zn1 and MCMgAl9Zn1, employing the finite element method using the ANSYS program. The computer simulation results correlate with the experimental results.Research limitations/implications: Presently the computer simulation is very popular and it is based on the finite element method, which allows to better understand the interdependence between parameters of process and choosing optimal solution.Originality/value: The possibility of application faster and faster calculation machines and coming into being many software make possible the creation of more precise models and more adequate ones to reality.
