Week - 5 - Modelling Spotwelds

AIM:

To simulate the spot weld joint by importing .k file in the LS-Dyna.

Procedure:

• To import the .k file for the given model.
• 
• Create the material and section ofr the given model.
• 
• 
• we should have to assign it to the part for the given model.
• 
• we should have to create the spot weld for the given model.
• 
• 
• we should have to create the material and section for the given model.
• 
• 
• we should have to create the Rigid wall for the given model.
• 
• we should have to give the intial velocity for the given model.
• 
• we should have to give the energy terimantion for the given model.
• 
• we should have to give the Terimination for the given model.
• 
• we shoud have to create the output for the given model.
• 
• we should have to run the .k file in the LS-Run.
• 
• 
• Energy
• 
• 
• we should have to create the solid model for the given model.
• 
• 
• 
• Energy

Comparsions of both cases:

Spot weld                                        Stress

Beam Element                                6.220e+02

Solid Element                                 3.437e+03

Conclusion:

In the case 1 the beam elements of spot weld has been deformed because the component strikesthe rigid wall with the high velocity the beamelements can not withstand the given high velocity 

In case 2 solid element of the spot weld will not collapse and shear stress is increased.
