A new approach to the simulation of microbial biofilms by a theory of fluid-like pressure-restricted finite growth

摘要: Abstract In general, the term ’growth’ characterises process by which a living body increases in size addition of mass. Living matter grows various different ways, triggered genetic and biological factors. addition, configuration grown space depends on its interaction with environment at boundaries. this paper, we deal mechanical constraints growth boundary body. Particularly, present model for such that residual stresses resulting from an isotropic deposition new material are continuously relieved hydrostatic pressure acting material. As example pressure-restricted fluid-like type growth, consider microbial biofilms growing between rigid obstacles geometrically confined environments. The presented concept unites two classical constitutive formulations large strain viscoelasticity finite growth. was implemented into element framework to illustrate performance several benchmark problems.
