TITLE AND ABSTRACT OF THE POSTER
Deterministic modeling used to tailor the mechanical properties of biopolymers
The study of mechanical properties of biopolymers is of major interest in many applications
related to food and non-food science. In food related topics, it is well admitted that varieties
of sensory descriptors such as crispiness, hardness, airy character are related to the food
mechanical behavior. Properties of biodegradable materials, as another example, used in
packaging or as single-use components are intimately dependent on the microstructure
features. In order to tailor the mechanical performance of biopolymers, a deterministic
approach is required to make the proper link between the structure and mechanical behavior
of biopolymers. This is done using a finite Element analysis. Starting from real
microstructures, generation of virtual structures is undertaken with the aim to quantify the
effect of microstructure descriptors on the mechanical behavior. The approach requires that
virtual structures share common features with real ones. Optimization of the mechanical
properties is then addressed and discussed based on available theories and experimental
investigations.
