contact pair v/s weld elements for modal and stiffness analysis of ladder chassis

Mahesh Agrani

For Modal and Stiffness(torsional and bending) of ladder frame chassis,  is there any significant difference in results when I use stick contact between frame and cross-members or when I use shell/rigid weld elements to connect cross-members and long members?

Hi,

 

Yes, I think you will see a difference with the stick contact and rigid welds.

 

Stick is a condition which tells the solver that two components should stick to each other when they come in contact.
