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.
