Measuring Acoustic Attenuation of Polymer Materials Using Drop Ball Test
… up to a few hundred kHz. Here, a simple drop ball mechanism is used to generate acoustic source waves in the kHz range, and the attenuation capacities of several solid materials are measured. The recorded waveforms substantially differ between materials. The results show that among the …

Field-responsive ('Smart') fluids for advanced automotive applications
… has been conceptualized, designed, modeled and tested in the present work. This adaptive energy absorbing material consists of an elastomeric foam impregnated with a field-responsive fluid such as a magnetorheological fluid or a shear-thickening fluid. Stable and inexpensive magnetorheological …
