How have you taken the values of tensile strength and compressive strength and others?? how you find that values?

Hello sir, I have a hexahedral multi-block structured mesh in ICEM CFD, I got some results from this mesh. Now, I have to do a mesh independence test. Please tell me which is the correct way to increase the number of mesh elements: Should I 1) Re-mesh the whole geometry with smaller element size 2) increase the number of nodes in each block. 3) increase the scale factor like 1.2 or 1.3 etc.... Thank you!

Thank you for the detail explanation. But, how can I incorporate nonlinear hardening instead of linear hardening? At 7:41, the derivative of function 'f' w.r.t 'Δp' would not be (-3G-H) for nonlinear hardening. For example: derivative of linear hardening (HΔp) is 'H' but for power hardening law [H(Δp)^n], its derivative would contain Δp itself. Should I replace 'H' with [n*H(Δp)^(n-1)] in 'dΔp' expression and solve accordingly? I am not sure if you got my point or not. I hope you would provide some help and suggestions. Thank you again. Waiting for the response...

Thank you for this vidéo i have à question which curve we can plot in this simulation exept force-displacement ????
Hi, thank you very much for these explanations ! One question though, how come the deformation increment is an input to the algorithm, when it depends on the deformation at step k+1? And tell me if I'm wrong, but it seems to me that this algorithm is not compatible with an explicit approach, given the sub-iterations required to calculate the plastic deformation increment.
First about the implicit solver, in each increment several predictions and corrections for the final displacement happen, named as iteration. In each of these predicted displacements the UMAT is called and the stress is calculated. Please see this video to understand the implicit flowchart better. kzread.info/dash/bejne/eXh7xbCQgqatZbA.htmlsi=iudM-PHv31iCZx_8 The explicit is totally different and we will discuss its algorithm and differences of UMAT and VUMAT in future videos.
as of 2:17 mean stress relaxation you are in strain control ? and it is not shown here but do you reach a limit in the hysteresis ?
Thank you soo much. Your videos are really great. I wish you the best.
the best video I have ever seen to explain the main problem in Abaqus
Before watching this video, please read some textbooks about numerical analysis.
Excellent explanation !
thank you sir for this video , i have modeled hollow sphere under internel radial displacement the material made of hyperelastic nehookena model, , sir how i can creat submodel for my problem ,pleases sir
Is your main model shell or solid. What about the submodel?
@@engineering_software i have used axisymetric for modeld hollow sphere,has an internel radius A and externel radius B
@@kar-dt1hk Why you don't follow the method of this video?
Very insightful and informative video. Thumb up 👍
Sir,In dynamic explicit if i normalize my step time do i have to normalize my input time (used in boundary condition)
When an amplitude is defined in boundary condition the timing is set by the step time.
THANKS FOR VALUABLE INFORMATION
So informative video. Thanks a lot for sharing your knowledge and experience.
Yes
Simple and good explanation. Thanks a lot
Sir how you calculated the energy for damage evaluation
Is same procedure can we apply for constitutive model of steel?
This constitutive equation (Mises Plasticity) is useful for most of metals. Just the material should be isotropic. For example it is not suitable for steel sheet produced by rolling process. In some cases the type of hardening should also change.
@@engineering_software i want to develop a UMAT for reinforcement rebar using Menegotto pinto steel model just to account hysteresis effect.
@@engineering_software i am taking about the stress-strain constitutive model of reinforcement rebar
Can you provide reference to learn continuum mechanics to understand in detail
Good 👍
Thanks for sharing this informative video ❤❤❤
Thank you for sharing ❤
could you please make a tutorial of thermoforming process on a composite material
Best channel in continuum mechanical
Amazingly explained but there is no further videos added in continuation 😢
Hope we can complete this series in near future.
how can i implement XFEM in ANSYS PLEASE HELP ME
very systematic explanation. Thanks a lot
Hi, can shell elements be used for evaluation of triaxial stress in thin sheet metal ?
Very Informative video, Have been using merge feature but was shocked to learn that there is embedded region too
Excellent work, if the materials is multidimensionnelle fiber we shoud do the same sbrotine or change it ??
If you mean that you have a laminate that each layer is unidirectional you can use this subroutine for each layer and assign material orientation to each layer based on fibers direction.
Very very good serie of videos. Thanks a lot. This series is the best I found about plasticity in the internet. Please consider doing the same for Drucker-Prager model. I am using your material with my students.Thanks again.
I am really grateful for your motivating comment.
How can I do same for cylinder Matrix please guide
Did you checked your email?
@@engineering_software yes I did and also gave you details but sir no reply from your side
@@sohamdesale9707 I replied 4 hours ago. please check and reply in email.
can you pleaes make ideo about static riks method , i have modeled hollow sphere hyperfoam under internel pressure, my probleme i dont know how plot pressure function deformed inner radius
Please check this video which may help: kzread.info/dash/bejne/YqKepMawl5rAaaQ.htmlsi=7zeKcIlQEjthjoWY
thank you so much .great work
Thanks for sharing
This code saved my time! thank you!
thanks, if the voice was real it was more enjoyable
Could you please upload video for randomly distributed inclusion in 3 D cylinder
The code is available please send us an email [email protected]
I checked it on web but it is for cube. Can I get is same for cylinder. I am ready to purchase.
@@sohamdesale9707 please check your email
Hi, thank you for your great videos. I have a problem with the running the script in Abaqus. I get the typeerror: 'float' object has no attribute '__getitem__' error for line 95. could you please help me with fixing the error?
