Katti Multiscale Modeling of Mechanical Responses in Bio-nanocomposites Structural composites in
nature are both nano-structured and nano-engineered. Their response
to stress under varying loading conditions is unique, and is superior
to that of engineered composites. Biomimetic design of nanocomposites
is thus an important current research field for design of advanced composites.
I will discuss multiscale modeling methodologies for predicting mechanical
responses in bio-nanocomposite systems such as nacre, the inner layer
of mollusk shells and bone. The models include the true crystallographic
symmetry, nanostructure, micro and meso structure. Modeling methodologies
from molecular dynamics to finite element methods are used.
