Abstract
The applicability of the Split Hopkinson Bar method to test PU based adhesive with thick bondlines is investigated. An adhesive is tested in tension, compression and shear with a Split Hopkinson Tension Bar (SHTB) and a Direct Impact Split Hopkinson Pressure Bar (Direct SHPB). Specifically developed sample geometries and corresponding experimental setups are briefly presented. Results for tension specimen obtained with SHTB are compared to results gained from tests using hydraulic machines (standard and VHS). The comparison shows that with the current setup, the SHTB is very well suitable to characterize the dynamic stiffness of the adhesive bond. Compression and shear tests have also been successfully performed using Direct SHPB and SHTB, however, due to limited space in this extended abstract, the compression and shear results will be given in the oral presentation.
