MARC recordSimple model of shock-wave attenuation in snow / Jerome B. Johnson.
| Title: | Simple model of shock-wave attenuation in snow / Jerome B. Johnson. |
| Author(s): | Johnson, Jerome B. |
| Date: | 1991. |
| In: | Journal of Glaciology. (1991.), Vol. 37(127) (1991) |
| Abstract: | Describes use of model to show influence of pressure impulse (integral of pressure over time interval during which pressure acts) and its geometry on shock-wave pressure attenuation, in addition to effects caused by mechanical behaviour of snow. Effects of shock-wave geometry are accounted for by calculating attenuation of plane, cylindrical and spherical shock waves in snow. Effects of shock-wave duration and initial pressure amplitude are analyzed by applying variable pressure-time profile shock impulse to snow and calculating pressure as function of shock-wave propagation distance. |
