specimen
Nonetheless, the simulation overestimates the response at large displacements
owing to the lack of strength degradation.
It is possible to make similar consideration for the ITS TM-3 and TC3 specimens.
The experimental reaction force vs. the controlled displacement relevant to the ITS
TM-3 specimen is illustrated in Figure 3.32a, whereas the numerical simulation of
