Outline of Final Research Achievements |
In order to predict the probability of frost damage at actual structure, this study aims to establish a thermodynamic non-equilibrium prediction model for frozen water volume taking supercooling phenomenon into account. First, the measurement to obtain the probability distributions of the freezing point and the instantaneous increment of ice content in the small element was carried out. Next, the investigation object was shifted to the small element continuum, the similar experiment to obtain the probability distributions was carried out. Finally, it had been verified that the proposed prediction model based on the probability distribution in the small element can be applied for the small element continuum from viewpoint of durability prediction.
