Hello,
This is my first question in the forum, sorry for my english.
I am involved in some modal correlation between test and numerical results with ansys. As a first step I have simulated weldings as a common nodes between the welded plates, and I have concluded that generally the local modes obtained by calculation are higher in frequency than the tested ones. So I understand this simulation is too stiff, and a better simulation of welding introducing some rotational stiffness should be necesssary. I have been looking for papers or reference documents talking about this problem but I have not succed.
Please, could anybody help me with this issue?
Thank you very much in advance for your collaboration.
