Abstract:
The strain-stress curve and the stress intensity factor are carried out using the machine MTS for Magnesium alloy AM50.Energy release rates(G)are evaluated based on the virtual crack closure technique and Griffith potential energy.Based on the relationship between Energy release rate(G)and stress intensity factor(K).And then stress intensity factor(K) is got.Comparison of stress intensity factors(K) of between the calculated values and experimental values is made,showing that they are in good agreement.
