Another metric to consider in the successful prediction of the stationary
response is the temperature along the length of the specimen. Figure
6.7
shows
the temperature along the length of the specimen for varying times during one
pulse sequence. As can be seen, there is a small variation in the model result at
1 s where the model overpredicts the experimental data. Also, in the fillet regions
of the specimen, there is a larger thermal profile difference in the experimental
and model results. This can be explained from the model assumption that the fillet
region is not included in the model, but may have had an effect on the temperature
distribution (see Fig.
6.5
near die interface). Thus, as the fillet region has a larger
cross section than assumed, the model predicts this region to have a slightly higher
heat generation and thus a higher temperature.
