corus - I believe you are exactly right. I do not have my FEA computer with me this weekend, but I have been thinking about what I did. And I am almost 100% sure you are right. When I calculated the dimensions I needed in Excel, I assumed diameters. When I put the coordinates in LISA, I was...
One more bit of information - I was reading the LISA reference manual on applying forces. It says when you apply a force to a group of nodes it will evenly distribute that load across the nodes. I have tried now with 2 different mesh densities, having different number of nodes across the top...
Here is a picture of what I am doing. (attachment)
It is an axisymmetric analysis - with Y axis symmetry. The bottom nodes are constrained to 0 displacement in Y. The top nodes have a 500lb force on them.
So, since it is axisymmetric, a rectangle drawn like I have it, should represent a...
I am new here. I hope this isn't too simple a question for you guys.
I am evaluating the LISA FEA package. I am trying to get the "textbook" results to verify I am using the software correctly. I have come across a strange problem. I am doing a 2D axisymmetric analysis. It is just a solid...
