Dear All,<\/p>\n

Good Day !<\/p>\n

I am trying to perform a simulation using explicit dynamics. The description is as below:<\/p>\n

    \n
  1. The sandbag would impact on the enclosure cover. <\/li>\n
  2. The sandbag weighs 15 kg.<\/li>\n
  3. The sandbag will act just like a pendulum.  <\/li>\n
  4. The impact would create a vibrations in the enclosure.<\/li>\n<\/ol>\n

    Below are my assumption:<\/p>\n

      \n
    1. Assign the denisty of a dummy model equivalent to that of sandbag<\/li>\n
    2. Assign the explicit property of sand (similiar to that of water)<\/li>\n
    3. Use either rope or trajectory to define the movement of sand, set the initial velocity of sand bag to zero and apply standard earth gravity. The sandbag will follow the trajectory or hung by the rope will hit the enclsoure. <\/li>\n<\/ol>\n

      Query:<\/p>\n

        \n
      1. Is it possible to define trajectory ?<\/li>\n
      2. Is it possible to define the property of sandbag as explicit material ? Or do I need to create material with sack thickness and filled with sand ? <\/li>\n
      3. Is it possible to define the rope property ? <\/li>\n<\/ol>\n

        Any help would be appreciated. <\/p>\n","protected":false},"template":"","class_list":["post-296035","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
