• J025024 Structural Analysis of Alveolar Duct Model Created by Phase-Field Method

抄録

The respiratory unit called lung parenchyma has ultimately fine and complex architecture, and is constructed from respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli, where the gas exchange of oxygen and carbon dioxide takes place. We constructed some cubic models of lung parenchyma with and without alveolar duct by using phase-field method, and conducted structural analyses to examine the strain field in parenchyma during expansion. The frequency distribution of 1st principal strain showed that the existence of alveolar duct result in slight change of strain distribution. On the other hand, it is found that the elements in the vicinity of alveolar mouths have relatively high value of 1st principal strain, which is one of the measures for the rupture of alveolar walls.
