Thank you Ma'am for this in-depth explanation. I would be glad if you could help me with the Cohesive Zone Modeling of a pull-out test simulation. Could you kindly share your email?
Where these lectures available or taken
Hi, where do I get the document??
Thanks for the content, very helpful. I'm having a hard time finding the equations for these parameters for concrete, can you help me?
Well explained, Plz make a playlist, so that it will be easy to go through to the lecture series.
Ma'am can you tell me what is plastic multiplier and what is it significance
Very informative. Thank you. Finally a channel dedicated to non linear FEM.

very nice content and very to the point explanations of concepts, please make more videos on other FEA and material modeling , vibration and fatigue concepts
1.
Thank you very much for such precise Videos!!!
S is distance in decomposition of traction?
Thank You! Great Explanation.
where word file..????
explanation was quite comprehensive. Thanks a lot !
How to calculate Plastic Multiplier ?
What is the formula for plastic multiplier ?
good explanation thank you
Thank you very much. You taught in an easily understandable way.
Hello, nice explanation. What software did you use to prepare this lecture ?
Can you please suggest a Textbook too Great video by the way
Hi mam, You said you had discussed about Lagrange multiplier method before. Is that video available in your channel?
Too much of theory.. it will get great if some practical knowledge of how to use this in a commercial finite element software..
Excuse me ! Could you give any tip to derive geometric stiffness matrix please ?
Hello ma'am, interesting lecture. 1) But I cannot sort it with date. Can you please help me. 2) please suggest book. 3) can you me your mail id, anything for formal conversation. Name :- Kaustubh My mail id is kaustubh.199@gmail.com
Hi, can you tell me where to get the full details for this problem? You mention a pdf? Where can I find this? Thanks
thanks for the video can you recommend a written source
Nice Explanation..
This video is not downloading
it's not correcte about the matrix F, so all the diagonal elements we add 1, so the diagonal is: 1+dx/dX , 1+dy/dY , 1+dz/dZ , an other way to exmailn that , The real F matrix of deformation is : F = I+Your matrix
content added by you is very nice and more worth than reading whole text book. really helpful. Can you please make some videos on explicit dyanamics and vibration domain
Thank you for sharing your knowledge. As you said cohesive zone modelling is not good if we don't know the crack path, then in such case which model is preferable..?
Use phase filed method for fracture wherein the crack trajectory will be based on the local strain energy density and would be realistic.
hello mam, your lectures are not in proper order can you add a number before them to make u derstand the order of lectures and flow...
Thank you for this amazing illustration for nonlinear geometry of truss element, but i really have a question regarding this video. my question is related to matrix B (see min 4:24) you write it equal to Bo+transpose(u)*H but according to the strain equation it must equal Bo+(1/2)*transpose(u)*H !! so i am asking where the half term has gone or disappear!!!! Am I Right or wrong?? and when taking the half in the derivation it completely change the final results. so please give an explanation or illustration for that ?
How is kc = 0 for D<g? Doesn't make sense
Thanks a lot. In the case of a citation, how can I cite your course or videos?
If both the contacting bodies are flexible. Which Young's modulus does the software consider for multiplying with the scale factor ?
There is a serious problem. The eigen value for 1st mode is 55.96 N instead of 5596 N. which is mentioned in the vedio.
Thank you very much, for uploading valuable video.
Woow I was looking for such to the point information. Please make on more FEA concepts including computational mechanics
hi, can you please tell what software and configuration you are using for this video?
please, can anyone explain to me where the 1/2 is coming from? i understand it has anything to do with linearization, but i can't find a proper explanation anywhere :( thx in advance!
If I remember correctly (not 100% sure), the number 1/2 is artificially added in the definition of the GL strain tensor (and analogue to that, Euler strain tensor), simply to have better mathematical behaviour in calculations. It's a normalisation factor, in other words. The reason linear analysis is always mentioned with that 1/2 is that it makes most sense in linear strain (small deformations) is to compensate for gamma (angle deformation) being equal to 2*epsilon on the same position in the tensor. I'm not an expert on this, so don't take it as simply true, but rather to help you find the answer in proper literature.
I will write the definition of the book here: the factor 1/2 being a normalization factor (whose significance is explained in a more general context in Section 2.2.7). Clearly, the material is unstrained at X if and only if E = 0 at X.
Sir, I want to analyse buckling and post buckling of a functionality graded plate using ansys but how to use power law in ansys , is a problem so make a video on this...thank u....
Actually, with a pole vaulter's pole, shouldn't it be "buckling", given the slenderness of the pole?
can u explain the mathamatical background of implicite and explicite method
Good
