Human lung simulants subjected to underwater explosions - An experimental investigation.

An experimental investigation was performed on human lung simulants to evaluate their response to an underwater explosive blast. The artificial lungs were instrumented with sensors to record changes in the internal pressure and strains for a specimen with and without a surrounding ribcage. The lungs were to-scale models representative of a 50th-percentile male.

Pressure signature and evaluation of hammer pulses during underwater implosion in confining environments.

The fluid structure interaction phenomenon occurring in confined implosions is investigated using high-speed three-dimensional digital image correlation (DIC) experiments. Aluminum tubular specimens are placed inside a confining cylindrical structure that is partially open to a pressurized environment. These specimens are hydrostatically loaded until they naturally implode.
