An experimental facility for detailed studies on energy absorbing components subjected to blast loading

Deformable components such as sandwich structures possess promising properties for use in protection systems. Detailed studies on energy absorption and fluid–structure interaction effects are necessary the application of deformable blast resistant design. In this paper, an existing shock tube facility has been extended with a transparent section to observe measure fluid flow structural response during transient dynamic loading. The extension was instrumented pressure sensors load cells force transmitted through component testing. design allows optical measurement techniques. Here, high-speed cameras were used both digital image correlation background-oriented schlieren imaging. Tests free-standing plates performed. A strong dependency observed between plate mass, thus velocity plates, measured upstream downstream components. tests simulated one-dimensional numerical model compressible interaction. accurately reproduced displacements experimentally. Overall, experimental set-up presented study proved be suitable detailed examination subjected airblast
