3-D finite element method for micromechanical analysis in fibrous composite material

The objective of this thesis was to study whether simplified three dimensional finite element models could be used as a micromechanical model for analysis of stresses at the fiber and matrix level while providing smeared composite properties for the global structural analysis. The mathematical model...

For considering interface cracks between the fiber and matrix, springs were modeled in the connecting nodes between the fiber and matrix on each of the three degrees of freedom.
