Finite strain theoryIn continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in infinitesimal strain theory. In this case, the undeformed and deformed configurations of the continuum are significantly different, requiring a clear distinction between them. This is commonly the case with elastomers, plastically-deforming materials and other fluids and biological soft tissue.
Membrane plasmiqueLa membrane plasmique, également appelée membrane cellulaire, membrane cytoplasmique, voire plasmalemme, est une membrane biologique séparant l'intérieur d'une cellule, appelé cytoplasme, de son environnement extérieur, c'est-à-dire du milieu extracellulaire. Cette membrane joue un rôle biologique fondamental en isolant la cellule de son environnement.
