dc.description.abstract | In order to understand the influence of biofilm's physical and microbiological structures on its mechanical behavior, a finite element model that describes the structural mechanics of a composite solid is linked to the outputs of the multi-component biofilm model UMCCA. The UMCCA model outputs densities of active biomass, inert biomass, and EPS for each compartment in a 2-D biofilm. These densities are mapped to the finite-element model to give a composite Young's modulus, which expresses the stress-strain properties of the biofilm by location. Sample results illustrate that using this methodology, one can identify the points in the biofilm that develop the highest internal stresses and that are most likely to fail first, leading to detachment. © IWA Publishing 2005. | en |
