Dynamic behaviour of dry and water-saturated sand under planar shock conditions

Abstract: . Dynamic behaviour of dry and water-saturated sand under planar shock conditions. International Journal of Impact Engineering, Elsevier, 2009, 37 (1), pp. This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may… Show more

“…4-5 and 6-7 show the speed of the shock waves for dry sands with porosity 41% and 22%, respectively, in both time intervals. From the graphs of the numerical results one can observe that the speed of the shock wave is faster in the wet sand than the dry sands (see [1]). In the contrary, the amplitude of the shock wave in the wet sand is approximately one-third of the one in the dry sands and it damps faster in the wet than in the dry sands.…”

“…Плотность сухого песка для различных фракций изменялась в диапазоне 1300−1600 kg/m 3 , скорости удара принимали значения от 500 до 1900 m/s. Средняя плотность образцов песка, содержащего 3% глины, в экспериментах [9] полученным по формуле (6) для грунтов с влажностью w = 0.1 и 19.2%. Отметим хорошее соответствие аппроксимации (6) результатам плосковолновых экспериментов [8] при предложенном способе определения констант сжимаемости начальной свободной пористости.…”

“…На рис. 7 представлены ударные адиабаты песчаной смеси с размерами частиц 0.1−1.0 mm начальной плотности 1730 kg/m 3 : светлые кружки, треугольники и квадраты соответствуют данным обращенных экспериментов [19], полученным при влажности w = 0.1, 10 и 18% соответственно; аналогично темные кружки, треугольники и квадрат соответствуют данным плосковолновых экспериментов [9], сплошная, штриховая и штрихпунктирная линии получены по формуле (6) в рамках модели трехкомпонентной среды. Из рис.…”
