Week - 3 Drop test Challenge

*For the below simulation the units are followed are gm-mm-ms.

Aim:

• This challenge aims to get a first-hand experience of the LS-Dyna simulation procedure for the arrangement given below.
  
  • 

Procedure:

1. The first step is to open the .k file in the LS-Prepost environment.
   • 
2. Then check the Part ID of different parts and change the name accordingly.
   1. Phone_Solid
   2. Floor_Solid
   3. Floor_Shell
      • 
3. Then creating Section cards for 3 different parts.
   1. Shell card- Includes the shell mesh of the floor and the thickness is given as
      • 
   2. Solid card - Includes the solid mesh of both phone and floor as two different cards.
      • 
4. Then from the Entity Creation toolbar, a Define_Box and a Boundary_SPC have been created.
   1. The Define_Box has been created for the elements of the phone.
      • 
   2. The Boundary_SPC has been created for both floor shell and solid and all motion has been restricted.
      • 
5. Then Elastic Material has been defined for both Phone_Solid and Floor.
   1. For the phone, the material is selected as aluminium and the material card is given below.
      • 
   2. For the floor, the material is selected as concrete and the material card is given below.
      • 
6. After creating the above cards, I referenced all the above in the Part_ID for proper material and section application.
   • 
   • 
   • 
7. Then to give motion to the phone we gave initial velocity in the negative z-direction to the box created before.
   • 
8. For establishing proper contact between phone and floor we have to give contact cards.
   • 
9. To save all the global energy data and animation data we have to add some database cards to the keyword manager, like glstat, matsum, and d3plot.
   • 
10. Finally, we can add a Control_Terminattion card to the keyword manager and assign the termination time as 10.
