No, that's not correct. Please note that if you are using SI (N and mm) units in Abaqus (as in this example), the the density should be in ton/mm3 not kg/mm3 as you assumed.
@@AElkady Thank you so much for your prompt response. Do you think the results will be different if I change the density in quasi static analysis? Moreover, can you plot the hysteresis response under cyclic loading for the given structure and its moment rotation curve?
جزاك الله كل خير يابشمهندس فيديوهاتك مفيدة فعلا.. بس عندي استفسار ازاي ادخل trilinear material curve by giving:_ fy_fu_E_ stain hardening and failure strain???
Sir While using step as static general, can we give a negative slope stress-strain curve in material property I'm modelling cfst column with a negative stress- strain curve subjected to cyclic loading How should I give material property and step module?
1) Newton is a force unit not a mass unit. 2) As per ABAQUS documentation, if you are using SI (N and mm) units, the the density should be defined in ton/mm3 units.
First, thank you for the informative presentation. Do you have a plan to do part 2 of this tutorial explaning the steel material in dynamic analysis? Again thank a lot and all the best Kind regards
Please check the two publications below regrading the definition of steel material for cyclic loading: ascelibrary.org/doi/full/10.1061/%28ASCE%29ST.1943-541X.0002166 ascelibrary.org/doi/10.1061/%28ASCE%29ST.1943-541X.0002964
Great videos sir I have watched all the videos in this playlist thanks for such useful videos. Sir, I have one confusion in defining the material for the plasticity I have given density, youngs modulus and poissons ration and yield plastic stress with corresponding strain 0 and in sub-option I used rate dependent(power law). Is this enough for the plasticity or I have to add UTS and respective strain?
First, thank a lot for your tutorial Sir. Can you explain, how to create material input for cyclic loading in Abaqus, for example using Nonlinear elasto-plastic kinematic hardening, or combination. regards Sir.

I mean, this has got to be one of the most thorough tutorials ever. Thank you, Mr. Elkady
best tutorial on abaqus
Excellent video. Thank you sir.
Well done bro🎉
Thanks for support sir

Dear Sir. Ahmed Elkady
I propose creating a video tutorial series on impact analysis simulation in ABAQUS.
Thank you, for the Vedio
Can you make a video on tensile test for dissimilar materials
I am sure but density if calculated in kg/mm3 should be 7.85e-6. I know it doesn't matter in static analysis but I just want to confirm.

Dear sir, if yield stress and ultimate stress is given, and E' taken as 1% of E. How to find ultimate strain and plastic strain?
Sir
While using step as static general, can we give a negative slope stress-strain curve in material property
I'm modelling cfst column with a negative stress- strain curve subjected to cyclic loading
How should I give material property and step module?
Thanks a lot for this tutorial, Why we don't use density in N/mm3?
1) Newton is a force unit not a mass unit. 2) As per ABAQUS documentation, if you are using SI (N and mm) units, the the density should be defined in ton/mm3 units.
The key is that in the SI (based in mm): Length (mm), Force (N), Mass (1=Tonne 10^3 Kg), Stress (MPa = N/mm^2), Density (tonne/mm^3)

And also I am doing a forming simulation in abaqus so there is any option to define rotation speed of the spindle?

@@AElkadythank you very much for the video, can you explain how to define a material like basalt bars in abaqus, thank you.
Thank you very much, but I think 7.85e-9 for mass density (ton/mm3) and not (n/mm3). what are the units that abaqus adopts?
Thank you, I understood the problem of the units, thank you very much.

Eu-Ey=0.18-(250/200000)
=0.17875
But here Eu is in percentage and Ey is value..
thanks for video its very useful, but how could be strain plastic 0.18 ? 470/200000 =?
the slope equation (young's modulus = stress / strain) is only for elastic range of slope not for plastic range
0.18-(470/200000)=0.17765~0.18
