Cosmos Shell Analysis

Hi all,

I am trying to run an analysis on the following question.

Basically, I am trying to create a split line in the middle of the shell, so that after I run the analysis, I can plot the deflection curve along the split line. I do not know if I need a split line in the first place.

The problem is that after I created the split line, I have trouble applying a pressure on the entire face because the split causes 2 shells instead of one. The pressure on top of the shell is a variable one.

Assuming I have a local coordinate system inserted at one of the corners (x-y-z) with z going downwards. z is the amount of deflection at a certain point of the plate at point (x,y). Let's say, I want to find the deflection along x=a/2 (assuming square plate of 'a' length).

I am using cosmos, and I know the analysis can tell me the max deflection and all, but what I need is only to plot a graph showing deflection of that line, x=a/2. The attach file will show what I mean.

Please help!!!!

Lu Song,

Are you using Cosmos/M or CosmosWorks?

If it's really a square or rectangular plate, and assuming the load is also symmetrical, then you should be able to use symmetry and run your analysis on one quarter of your plate. The analysis runs much faster and you can see the edges you are interested in.

Not being a serious Cosmos user, I don't know how to tell the program to output the deflections along a given line.

The attached file did not show up on my reader. I don't thnk you are supposed to attach large files anyway. It would be better if you had some place that you could post it where people could download it.
