Is it possible to obtain frequency response function of a system with nonlinear phenomenon?

Recommended Posts

Hi,

 

I am looking for the right PRE-PROCESSING TOOL and SOLVER to solve this problem.

 

My problem is attached as a picture.
 
Two plates are spot-welded.
 
I assume top plate is excited by horizontal and vertical harmonic loading.
 
I think Stick-slip phenomena appears due to friction between top plate and bottom plate and Slap phenomena appears due to vertical force.
(slap phenomenon will occur in this system when the amplitude of the relative displacement is larger than the natural gap distance between the two plates.)
 
RADIOSS is known as the best structural analysis solver for solving highly nonlinear problems under dynamic load conditions.
 
Is it possible to obtain frequency response function of a system with nonlinear phenomenon by using (Hypermesh or Hypercrach) and RADIOSS ?
