    boundary conditions

    yes it seems that the boundary conditions are correct, however could there just be a internal error due to the eigenvalue? From the eigenvalue how do i determine the critical load? I have added a shell edge load of magnitude 1000000 from this i then multiply it by the eigenvalue is it correct...

    Any other suggestions as i am having great difficulty with the boundary conditions?

    I havent studied that.

    boundary conditions

    Thank you. I have performed mesh convergence and this is the result it converges to. Any other suggestions which might help. are the boundary conditions simulted for a simply supported plate with compression correct from the picture. The % error from the reults is very high and i want to get it...

    boundary conditions

    Basically ive now changed the magnitude of the shell load to 1000000. And applying at both ends to represent a compressive strength is that correct to do? U3 = 0 on all edges. while U1 = 0 on the top and bottom edges, U2=0 on the left and right edges. Picture illustrates the boundary conditions...

    boundary conditions

    The Shell edge load is of magintude 1 and is simlar to a moment. Do you think i should make the magintude higher. The initial boundary conditions which i inputted to get the high value for the eigenvalue were: A) U3 ticked on all side B) U2 ticked on two parallel sides C) U1 ticked on one of...

    boundary conditions

    Thank you for the response. Basically its a thin aluminium plate of 400x400x10 mm which is being simualted to determine its buckling characterisitics. So what it is a simply supported plate and im having trouble with the boundary conditions as then i want my result to be compared to the...

    boundary conditions

    Hi Just wanted to ask i want to simulate a thin plate and determine the buckling load from the eigenvalue. The eigenvalue i have determined is very high to the power of 9. Wanted to ask its a simply supported plate, what should be the boundary conditions. Thank You
