Identification of neutron irradiation induced strain rate sensitivity change using inverse FEM analysis of Charpy test
Result description
A simple methodology how to obtain additional information about the mechanical behaviour of neutron-irradiated WWER 440 reactor pressure vessel steel was developed. Using inverse identification, the instrumented Charpy test data records were compared with the finite element computations in order to estimate the strain rate sensitivity of 15Ch2MFA steel irradiated with different neutron fluence. The results are interpreted in terms of activation volume change.
