Multiscale Modeling and
Failure of Composite Materials
Homogenization
and Uncertainty Analysis for Fiber Reinforced Composites Complex
material behavior of a composite material can be modeled using a
homogenization method without modeling individual fibers and matrix. This
research focuses on homogenization of nonlinear material behavior of
composite material. In addition, the effect of uncertainty in the micro-scale
on the macro-scale will be investigated.
eXtended
Finite Element Method (XFEM) to Model Failure in Composite Materials XFEM
allows strong (cracks) and weak (material interfaces) discontinuities to be
represented independent of the finite element mesh. Costly remeshing
associated with modeling crack growth with traditional finite element methods
can be avoided in this method. The interaction between the matrix and fibers
in the presence of a growing crack is the main interests of this research. |
