摘要：

This paper demonstrates how the usual standard tests for characterization of mechanical stiffnesses of glass fiber-reinforced composites can be enhanced by means of photogrammetry. This method allows to reveal and study local imperfections and damage inherent to the production process of the material (e.g., weaving flaws) as well as during loading (e.g., fiber breakage). Moreover it is capable of quantifying the impact of these imperfections on design and construction in terms of (local) deformation or overall stiffness. (c) 2007 Published by Elsevier Ltd.
