Thin -Film Adhesion Measurement by Laser -Induced Stress Waves
Based on the theoretical and experimental parametric study results, the planar tensile sample geometry is modified to a triangular prism so that a high strain rate shear wave is generated and then allowed to impinge upon the test film. By allowing the initial longitudinal wave to mode convert to a …

Development and proving of a split Hopkinson pressure bar used for high strain rate materials testing
… rates are not adequate as oscillations and stress waves are set-up within the testing apparatus. These oscillations and stress waves foul the transducer reading, thus making the data obtained unusable. To overcome these limitations the split Hopkinson pressure bar (SHPB) was developed. A …
