...H. E. Cho; H. M. Zbib; M. F. Horstemeyer This study presents an irradiation-dependent internal state variable (ISV) elastoviscoplasticity-damage constitutive model that accounts for nuclear irradiation hardening and embrittlement of the irradiated polycrystalline materials. The irradiation effects...

... simulation results of various fatigue tests are presented by varying mixture constituent properties. This is to demonstrate that the model can capture material-specific fatigue damage characteristics at least in a qualitative manner at this stage, which can be quantitatively validated with some specific data...

... the effect on strengths/behavior of the CSS samples due to embedded PFCS. Then carefully planned experiments are conducted to investigate the ability of the embedded PFCS to monitor the stress/strain levels and detect damages in CSS using modal analysis technique. The tensile tests show that both the average...
