hello,
I am modeling a structure with shell elements and I am having very high local stresses in the areas
where perpendicular shells are connected as you can see in the attached file. In the real strucutre
the webs are welded to the rest of the structure.
I've heard that perpendicular shell elements give pessimistic results. Is this issue relevant in my
model? Should I use a more detailed mesh?
To understand what I am talking about please look at the attached pdf.
My question is how relevant these modeling issues are, and which is the best way to model this
kinf of problems.
PD: The results shown in the attached file are from a random analysis.
thanks
