Dynamic Finite Element Analysis of Third Size Charpy Specimens of V-4Cr-4Ti
A 2-D finite element analysis (FEA) of precracked, one-third-scale CVN specimens of V-4Cr-4Ti was performed to investigate the sensitivity of model results to key material parameters such as yield strength, failure strain and work hardening characteristics. Calculations were carried out at temperatures of −196°C and 50°C. Dynamic FEAs were performed using ABAQUS/Explicit v5.4. Finite element results are compared to experimental Charpy results from the production-scale heat of V-4Cr-4Ti (Heat #832665) as a benchmark. Agreement between the finite element model and the experimental data was very good at −196°C, whereas at 50°C the model predicted an absorbed energy slightly below the experimental value.
