Abstract

Digital image correlation technique is a non destructive testing (NDT) tool for measuring deformation and failure of material have been used in this study over conventional methods such as strain gauges and extensometer. ASTM and other institutions have developed specific standards for composites. In the aim to inform the developed models of finite element/numerical and analytical, tensile tests were conducted on composite adherend and polymer adhesive specimens to obtain the stiffness and strengths of all constituents. Materials used for the testing campaigns are Glass Fiber Reinforced Polymer (GFRP) and Carbon Fiber Reinforced Polymer (CFRP) as well as adhesive materials for bulk testing Araldite 2015 and Sikalfex 292. The digital image correlation (DIC) technique is utilized for the characterisation of the constitutive and failure behavior of the constituent materials, with focus on the composite and polymer adhesive material system.
