3d Deformation Measurement Using Stereo- Correlation Applied to Experimental Mechanics
نویسندگان
چکیده
Optical methods that give displacement or strain fields are now emerging significantly in the mechanical sciences. In the Material Research laboratory at École des Mines d'Albi, we have developed a binocular stereovision system that can be used a) to measure the 3D shape of a static object or b) to measure the deformations of an object undergoing some 3D mechanical or thermal stress. In this paper, we will focus on two current applications of the stereo-correlation method: 1. the measurement of local deformations on stamped sheet metal parts, 2. the measurement of 3D displacement and strain fields on an inflated elastomer membrane undergoing large elongations (>100%).

A Generic Synthetic Image Generator Package for the Evaluation of 3d Digital Image Correlation and Other Computer Vision-based Measurement Techniques
Stereo digital image correlation (also called 3D DIC) is a common measurement technique in experimental mechanics for measuring 3D shapes or 3D displacement/strain fields, in research laboratories as well as in industry. Nevertheless, like most of the optical full-field measurement techniques, 3D DIC suffers from a lack of information about its metrological performances. For the 3D DIC techniqu...
متن کاملBending Analysis of Thick Isotropic Plates by Using 5th Order Shear Deformation Theory
A 5th order shear deformation theory considering transverse shear deformation effect as well as transverse normal strain deformation effect is presented for static flexure analysis of simply supported isotropic plate. The assumed displacement field accounts for non-linear variation of in-plane displacements as well as transverse displacement through the plate thickness. The condition of zero ...

In this paper, dense 3D measurements are tested by using parallel stereo camera system with fisheye lenses when the measurement space is almost spherical at the distance of two or three times of baseline length from the stereo camera system. The 3D measurement method and the experimental results are introduced.
متن کاملA New Quasi-3D Model for Functionally Graded Plates
This article investigates the static behavior of functionally graded plate under mechanical loads by using a new quasi 3D model. The theory is designated as fifth-order shear and normal deformation theory (FOSNDT). Properties of functionally graded material are graded across the transverse direction by using the rule of mixture i.e. power-law. The effect of thickness stretching is considered to...
