Dynamic thermal cycle ambient simulation under mouth motion; a finite element analysis

The aim of this study is to analyze the experimentally established thermal cycle test experiment using the Finite Element Analysis (FEA) method. Within the scope of this study, the thermal-mechanical behavior of the pure titanium test material at minimum and maximum temperature environments was analyzed in the simulation environment occurred at 1/1 scale with the experimentally established parameters. Pure titanium test materials that different geometry were kept at 5°C temperature for 30 seconds and then exposed to 65°C environment during 2 seconds change period. Thus, 1 thermal cycle was completed under mouth motion simulation. The results obtained showed that the temperature distribution in the circular test sample exhibited a more homogeneous distribution behavior than the square test sample. This result reveals the importance of the geometric structure of the test sample in the experimental environment conditions. Therefore, the use of a circular test sample in in vitro laboratory thermal cycling experiments will increase the accuracy of the results obtained under mouth motion simulation tests. As a result, the results obtained in this study are expected to mathematically guide the selected parameters in in vitro and in vivo studies.
