  • The dynamic response of the 57 vol./vol. % dense spherical silica particle-polyethylene glycol suspension at high pressure was investigated through short pulsed laser induced shock experiments. The measured back free surface velocities by a photonic Doppler velocimetry showed that the shock and the particle velocities decreased while the shock wave transmitted in the shear thickening fluid (STF), from which an equation of state for the STF was obtained. In addition, the peak stress decreased and the absorbed energy increased rapidly with increasing the thickness for a thin layer of the STF, which should be attributed to the impact-jammed behavior throughmore » compression of particle matrix, the deformation or crack of the hard-sphere particles, and the volume compression of the particles and the polyethylene glycol.« less
  • Specimens of glass fiber, phenolic foam, and extruded polystyrene foam insulation with moisture contents ranging up to about 25 percent by volume were mounted in the roof of an experimental building. The interior of the building was maintained at about 21/sup 0/C and normal weather conditions prevailed outside. Thermocouples were located at the upper and lower surface of each insulation specimen and at the quarter points of some specimens. A calibrated heat flow meter was used to measure heat flow through each specimen continuously for a period ranging from about 7 1/2 to 18 months for wet specimens and somewhatmore » less for some of the dry ones. Heat flow rates were plotted against temperature difference using daily arithmetic averages in most cases; two-week averages were used in a few cases. For open-cell and fibrous insulations of 20 percent moisture content, heat flow rates exceeded rates for dry insulation by a factor of two or more. The data points were scattered. Inspection suggested that this was partly owing to moisture distribution, which affected the rate of heat flow at a given temperature difference. Measurements at the quarter points provided information about temperature gradients along the path of heat flow, and hence about moisture distribution in the insulation These results suggested that moisture migrated to the upper layers in the wintertime, leaving the lower layers nearly dry. Ratios of heat flow in wet and dry specimens were in fairly good agreement with those obtained by other investigators.« less
  • The coupling of a dynamically adaptive Eulerian Cartesian detonation solver with hierarchical time step refinement to a Lagrangian thin-shell finite element solver with fracture and fragmentation capabilities is presented. The approach uses a level set function to implicitly represent arbitrarily evolving solid structures on the Cartesian mesh. The auxiliary algorithm used to efficiently transform the shell solver mesh on-the-fly into a distance function is sketched briefly. We detail the derivation of the employed engineering combustion model that eliminates the numerical stiffness otherwise inherent to detonation waves and describe our approach to modeling fracture. The thin-shell solver utilizes a subdivision finitemore » element discretization and achieves element separation with interface edges and a cohesive law. For method validation and benchmarking, the simulation of the deformation of a circular thin copper plate under impulsive pressure loading is presented. As a realistic computational application, we consider a three-dimensional setup in which the passage of an ethylene-oxygen detonation wave induces large plastic deformations and rupture of a thin-walled tubular specimen made of aluminum. Special attention is paid to the verification of the hydrodynamic loading conditions. The computational fluid-structure interaction results are found to be in agreement with experimental observations« less
