I followed your tutorial to practise stifferd plate structural modelling in ANSYS. Many thanks for the clear instructions.

Excellent analysis.

Thanks you very much, the procedure is very clear!

Dear meric büyükkoyuncu, Thank you very very much for the tutorial. It helped me to validate my work. I am eagerly waiting for your next video. I hope you will arrange some time to help others from your busy schedule. May Almighty reward you for your good deeds. Please keep up the works... I would also like to ask you if you can elaborate damage analysis of composite stiffened panel with skin stiffener debonding/delamination using the Cohesive Zone Element method.... Best wishes...Rayhan S.B.

Thanks for the great video. Also I have a doubt, does the final result (F vs disp) depend on the scale factor of 0.004, will the chart be very different if the scale factor was different?

This video is very helpful .. i need to work on all combinations of local and global eigenmode (buckling of subpanel and stiffeners) and sin/ cos functions also with half waves. could you please guide me

How do I contact the surfaces in case of T stiffeners? Is it okay if I select the web edge as a target and the flange face as the contact body by making another contact in ANSYS? I would be glad to get an answer.

When you apply "Surface From Skecth" Shell elements are automatically created. There are 2 options as Shell 181 and Shell 281. In the video probably Shell 181 is used.

Hi Prabhhu, Sometimes load direction can be wrong. Sometimes you may define plasticity properties in the eigen-value buckling analysis. Sometimes applied load can be too much compared to the structure. You can check these firstly.

Sir, can you please tell us how to calculate initial buckling load (74.5KN) here? I modelled same as you said and I got Loadfactor = 1.3453, Applied load = 100N/mm so, 1.3453*100 = 134.5 N/mm. our panel edge dimension is sum of plate and stiffener edge that is 440 + (28*3) = 524mm. hence buckling load is 524*134.5 = 70478N = 70.478KN. Is this correct ?? please correct me if i am wrong sir.. thanks in advance

Thank you for your comments. I don't know another method to find ultimate load. Because this is iterative solution (It has to be), so you need to have this graph to see the ultimate load. This graph is the conclusion of the reaction of the plate to the given displacement . This reaction is a outcome of displacement on the plate. Therefore I don't know another method whether another method is exist or not.
