Molecular dynamics simulation study on the tensile behavior of FeC alloy
In order to investigate the effects of temperature and strain rate on the micro-mechanical properties of FeC alloys,molecular dynamics methods were used to simulate the tensile properties of FeC alloys.The stress-strain curves of FeC alloys at different temperatures and strain rates were ob-tained and analyzed,and the data was processed using MATLAB.A mathematical model was estab-lished to predict the elastic modulus and yield strength of FeC alloys calculated on the basis of temperat-ure and strain rate.The results show that the maximum absolute errors between the simulation and the prediction values by the mathematical model of elastic modulus and yield strength are 2.680 GPa and 0.079 GPa,respectively.The maximum relative errors are 1.680％and 0.737％,respectively.The math-ematical prediction model can effectively predict the elastic modulus and yield strength to a certain extent.
