Column's Buckling Load and Deflection Using 3D FE Analysis by Abaqus

This is the three dimensional finite element analysis by Abaqus to find buckling load and deflection of a slender column.

Thanks for great video

[@muhammadaimanbinyusop2984]

Hi friend i have completed modelled and get the result using buckling analysis. but the problem is how can i produce the graph for load-displacement and stress-strain??? really hope you can help me

[@alifezizi230]

so good

[@alifezizi230]

do you have video for buckling hollow steel column?

[@UsamaAlSaffar]

Unfortunately, I don't have one

[@chiraghingad3822]

Hello video was great..just one doubt after analysis when i am changing boundary conditions to fix fix then also i am getting same ans can u help me in that

[@raghdahal-chalabi6323]

Thank you for the great video, it is just what I need. I have one question, how can we simulate different support scenarios, i.e fix-fix column. I am trying to simulate eccentric load on column, can u show this aswell please.

[@UsamaAlSaffar]

You can use the same above model but add more restrictions to the rotation and translation to simulate fixed end case

@@UsamaAlSaffar Hi Sir, in this video is pin pin condition right?

[@UsamaAlSaffar]

boonkeat wong right

[@boonkeatwong4243]

@@UsamaAlSaffar Hi Sir, for fixed-fixed condition, I apply at the same boundary condition position as what you did above and ticked all u1u2u3, ur1,ur2,ur3 at both end, but still couldn't get the close value compared with Euler buckling hand calculation formula... I can get for Fixed- Free and Pinned- pinned, but not for Fixed-Fixed and Fixed- Pinned.. Do you have any suggestion.. TQ Sir and appreciate your answer :)

[@chiraghingad3822]

@@boonkeatwong4243 hey bro can u let me know how u did it for fix free cz i am not getting it ..in same model did u changed bound cond or made new model

[@jackman3519]

Hi there, what if the eigen value is negative, what does that mean? does it mean the structure will not buckle or i did something wrong?

[@nj5587]

Can you do a video for a reinforced concrete column?

[@UsamaAlSaffar]

Maybe later .. I’m super busy these days

[@rajneeshkumar1881]

But where is the load vs deflection plot?
Please make a second part of it to plot load vs displacement.

[@leozhang299]

The deflection in the static analysis seems only occured in vertical direction, no lateral value. :(

[@UsamaAlSaffar]

There is a small value of lateral deflection, if you would like to see it clearly, try to reduce the column's stiffness.

[@krunalsinhvirpura455]

Why You’ve select quadratic instead of Linear in geometric order???

[@UsamaAlSaffar]

this is because it's closer to the deflected shape from the buckling equation

[@radwancheikhmous5547]

@@UsamaAlSaffar could it be to take the (p-delta) effects into account?. If not, could you please confirm if Abaqus analyzes structures following second order analysis by default?

[@rawaasaadi7215]

ليش الquadratic مو لينير ممكن جواب

[@UsamaAlSaffar]

this is because it's closer to the deflected shape from the buckling equation

السلام عليكم استاذ
اذا اريد استخدم وحدات ملم وmpa شلون؟

[@UsamaAlSaffar]

بان تعرف كل الابعاد بال mm وتسلط ال load بوحدات N وتعرف معامل المرونة بال MPa

@@UsamaAlSaffar نعم استاذ كيف يتم هذا التعريف وليس هناك طريقة معينه لذلك

GREAT JOB SIR
NOW HOW IF I WANT TO CALCULATE THE CONTACT FORCE？

شكرا دكتور ما قصرت
ممكن الفيس مالتك حتى اتواصل وياك اذا احتاج شي
