Characterization of a structural adhesive by Digital Image Correlation

Abstract

In the recent years, structural bonding takes an important place in assemblies techniques used for the automotive design. The next step to optimize the use of adhesive in car structures is to realize accurate finite element simulations of behaviour until failure of bonded joints. These kinds of calculations are only possible if fine behaviour and failure models are provided into the finite element software. In these works, tests on bulk adhesive specimens are realized to characterize the mechanical properties. 2D and 3D Digital Image Correlation are used to investigate the behaviour and failure of the shear and tensile specimens. ©2010 Society for Experimental Mechanics Inc.
