what kind of shell buckling tutorial you want to see next? comment below !

Thanks a lot!

Really nice video! I worked for some time on composite and deployable boom for small satellite and I found this video really good for someone starting his first steps into Montecarlo analysis with Abaqus. I am currently referring this to a group of students here at the University of Glasgow who are working on developing a high power rocket and I am helping them with the FEA side. Would be amazing if your thesis/paper on which this video is based is available since such analyses will be done for sure in the next months. By the way my name is Daniele Barbera and I am a Research Associate at UofG.

Hi Daniele, Thanks for your comment. It is really appreciated. My PhD thesis is here: www.researchgate.net/publication/337465846_ROBUST_DESIGN_OF_BUCKLING_CRITICAL_THIN-WALLED_SHELL_STRUCTURES If you or your students have any further questions let me know.

Thank for you video. It helps me a lot. It would be better if there have subtitles

hey , thanks for the advice. I will look into it. also I have now a much better mic than in the earlier videos. Kf you want to see anything Monte-Carlo related, let me know.

Super helpful video. I was wondering how you could script varying the thickness of shell faces randomly.

Create a list of faces, make a loop for those faces and then at each face create a random thickness?

Thank you very much for the video. It has been a great help. There are no other videos like this. I would like to ask you a question. How could you know the minimum number of simulations required for the method to be considered valid? How to validate or calculate the validity or convergence of the application of the method? Again, thank you very much

you could check the convergence of the mean or the variance of your target variable

Thanks for this video. It was very helpful. Just one question. How to use model parameters such as density as a random variable in reliability analysis?

i would recommend to model it similar to the coordinate and the load at 6:20 if you like you can give me your example and i can make a video using the First-Order Second Moment method (FOSM)

Hello. Thank you for the interesting video. I would like to know if you can introduce material variability in FRP cylinders in a similar way? Would appreciate your advice on it.

you mean liker fiber angle variation and thickness variation ?

@@hnrwagner Yes. Mostly fibre data like: tensors data from local misalignment? :) The thickness variation can be a cherry on the cake.

thank for this video. I have question in application of montecarlo in abaqus with section and modules of elasticity are random can you help me .

Good morning sir. I am researching a probabilistic analysis of soil consolidation in which the properties of the soil are not sound the same from one element to another of the mesh (such as modulus of elasticity E and hydraulic conductivity K ) they are considered as random variable generated by a function using MCS. How to introduce this variability into the abaqus software.
