Abstract

The stress-strain relationship of adhesive material is important as an input for numerical simulation. In this paper, a series of quasi-static experiments to measure the stress-strain relationship of FM94 adhesive material is reported. The experiments include the bulk tension test to obtain the tensile property and the V-notched beam shear test to obtain the shear property. The FE simulation with the Drucker–Prager model shows good agreement with experimental results. Moreover, further numerical results of adhesive joints show it is not always proper to use the Von Mises model to simulate adhesive joints as some previous studies proposed. The experimental results clearly show that the effective yield stress of adhesive materials is different for tension and shear, which disagrees with the Von Mises model often adopted in simulation.
