Identification of adhesive properties in GLARE assemblies using Digital Image Correlation

Abstract : An experimental-numerical methodology is introduced to identify the parameters of a cohesive law of an adhesive layer within a joined assembly on the basis of kinematic data provided by digital image correlation. Nonconventional experiments on joined samples were designed to generate within the assembly and the adhesive film complex strain and stress states close to those expected in service and up to complete debonding. The modeling is developed with reference to the observed sub-domain in which the experimental boundary conditions are prescribed. The non-linear behavior of the adhesive layer is described as a finite thickness interface endowed with a mixed-mode cohesive law whose parameters are identified so as to match at best the measured displacement field.
