Stress concentration around an atelectatic region: A finite element model

Highlights • We use finite element modeling to study the effects of atelectasis. • We modeled the lung mechanics using non-linear large deformations and networks of non-linear springs with hexagonal-like and Voronoi-like arrays. • We concluded that atelectasis may lead to an overinflation of surroun...

Zusammenfassung:	Highlights • We use finite element modeling to study the effects of atelectasis. • We modeled the lung mechanics using non-linear large deformations and networks of non-linear springs with hexagonal-like and Voronoi-like arrays. • We concluded that atelectasis may lead to an overinflation of surrounding region.
