Reinhard Pfriem,Christian Lehmanninvestigation is to assess the possibility of using these transducers for experimental modal analysis. Piezoelectric disks were therefore used in the laboratory to extract the natural vibration frequencies and mode shapes of an aluminum cantilever beam and of a steel arch. The results are compared w

l head models exposed to blast cannot be accurately predicted. The cavitation pressure of fluids is highly variable, depending on the presence of impurities in the fluid and the presence of dissolved gasses. In this study, a modified Compressive Split Hopkinson Pressure Bar (CSHPB) apparatus incorpo

120/s to 3490/s. Test results showed that energy absorption per unit volume of Eco-Core (11 MPa) is far superior to other tested commercial core materials (more than twice of Balsa wood the nearest material). The energy absorption per unit mass of Eco-Core (22 kN m/kg) is marginally better than othe
