Micromechanical modelling and experimental investigation of random discontinuous glass fiber polymer–matrix composites
Source abstract
Abstract
Videomeasurements were used to estimate the damage in chopped random glass fiber polymer–matrix composites. In order to predict the overall mechanical behaviour, voiding evolution induced by fiber debonding is incorporated into a micromechanics-based constitutive model. The comparison between the experimental data and the numerical predictions shows a very good agreement.
