Week - 3 Drop test Challenge

Aim: to simulate a drop test of the phone with an initial velocity 

Procedure:

1. Open LS- Prepost >> import the keyword file
2. Delete the unwanted parts -----Part Data>>Select the unwanted part>> delete

3. Assign Material to the parts----Keyword manager >> All>> MAT>> Assign materials to phone and concrete wall

5. Go to create entity >> set data >> SET_SEG>> Select pick by part>> assign SET_SEG to both phone and concrete wall

5. Boundary conditions--Concrete wall Go to create entity >> Boundary >> spc >>Create>> Select pick by part>> select the rigid wall >>arrest all DOF >>Apply

6. Phone -----Go to Keyword Manager>> Initial>> initial velocity>> Select phone >>Give velocity in z axis

7. Go to keyword manager >> ALL>> Section >> Solid >> Define solid section

8.Go to keyword manager >> ALL >> Select phone as slave and concrete as master >> Accept

10.Go to keyword manager >> All>> database >> binary_D3 plot >> time step 0.05sec

11.Go to keyword manager >> model check >> keyword check

Results

the internal energy of the phone increases when the phone comes in to contact with the concrete wall.
