Notes:
In this paper the dynamic mechanical behaviour of two epoxy adhesives for structuralbonding is investigated. The study has been focused on the influence of the strain rate on the tensileand compressive strength of specimens made of adhesive. The experimental tests have beenperformed with an hydraulic universal testing machine and a tension-compression Hopkinson bar.The results of the tests show that the σ−ε curve rises significantly increasing the strain rate. TheCowper-Symonds and Johnson-Cook models of strain rate dependence have been used to fit theexperimental data with unsatisfactory results, thus a poly-linear fit has been adopted
