Application of Stereovision to the Mechanical Characterization of Refractory Ceramics Reinforced with Metallic Fibers

摘要

Optical methods that give displacement or strain fields are now emerging significantly in the mechanical sciences. Much work has been carried out on two-dimensional (2D) displacement/strain measurement from a single camera but the proposed methods give only in-plane strains. We have developed a binocular stereovision technique that can be used: a) to measure the 3D shape of a static object or b) to measure the strains of an object undergoing some 3D mechanical or thermal stress. In this paper, we present the application of the stereovision technique to the mechanical characterization of refractory ceramics reinforced with metallic fibers.
