Modelling fracture in fibrous microstructures

PDF Version Also Available for Download.

Description

This work describes some complementary studies directed towards micromechanical modeling and simulation of the statistical fracture process in composites with fibrous microstructures. A few studies involve combining efficient computational stress analyses and piezospectroscopic measurement techniques to quantify interface deformation around a single break in model composites. It is shown how estimated interface parameters can be used to predict activity around more complex break arrangement in much larger composites. The final studies involve incorporating these experimentally refined stress analyses into large scale simulation for statistical predictions and subsequent analytical modeling of composite fracture.
