Abaqus: Hyperelastic material constants evaluation from test data 

Great introduction! You have saved me the grief of installing software and not knowing where to start.

Very good demonstration of curve fit for hyperelastic material. Thank you!

Commenting just to let you know that you are doing great job for us especially by going deep. We appreciate that.

Thank you very much!!!!! I greatly appreciate what you are doing! I watch your lectures and videos and they are a great help to me! Please continue doing the good work! You are inspiring!

My hearty wishes for your channel, its a very useful video

Thanks a lot for uploading the video! As a suggestion for similar videos, you could make a video of an axyssimetric rubber seal being compressed by rigid surfaces. It will not be difficult to do and people will like it

Thanks very much for you kind work! It is very helpful!!!!!!!!!

thanks for uploading the video .Can you upload the video for defining the material properties of foam.

Thanks for the sharing such precious information, Will you please make a video on the material constants for steel subjected to cyclic loading. Material parameters for isotropic hardening and kinematic hardening.

Great Job!

it's been very useful seeing this movie. thank you so much. could you please make a video to show us how we can interface Abaqus with Matlab?

hello Thank you for preparing these valuable videos. I would like to ask you to make a video for abaqus/matlab interface. call the abaqus with matlab. run the abaqus with matlab. and import the result from abaqus to matlab.

Thank you sir How to simulate vibration effect on a model of two different homogen ous structures

Thank you sir for this informative vedio, Can you please upload video for Anisotropic Hyperelastic materials? How can I find the parameters for Holzapfel model, C10, D,k1, k2, and kappa

what determines whether a material is stable or not? (it's shown in your Stability Limit Information window). Is it related to Drucker's stability criteria?

Thank you very much

Thank you. Nice tutorial

Sir, Have you published your data in any Journal or report ???? To cite as reference !

Thanks for your videos. I learned a lot from you. How about anisotropic materials ?

Good content, but an ad every 2 minutes means I'll not be visiting your channel again.

is it possible to share the inp file shown at the end of the video ?

thank you very much sir!

Hi sir, I would like to ask you for some help. I am using hyperfoam to model Polyurethane. I am inserting a compression data set to fit a 2nd order strain energy potential. The model fits the data very well for strains from 0.1 to 0.8. However, my model does not catch the elastic behavior coming from the experimental data. the experimental stress is double that predicted by the model in the strain range from 0-0.1 (the range of cell walls bending). This appears clearly when I run my simulation and also when I evaluate the material. Is there any suggestion to solve this issue? thanks.

I have 2 sampe data (uniaxial and plannar test data).. And i can not find the stable material for all the material models, what should i do?

Can I put damage model, in hyperelastic behaviour with just unidirecional data sheet? If Yes, how?

Thank you for your lecture, sir! I have a small question relating to the test. Could you please let me know What type of stress & strain is used for the test data? I mean they are mises equivalent stress/strain or stress components? Thank for your help, sir!

Great! Thanks a lot.

Can you give me the reference of the book/text from which you have used the polynomial equation in 2:50 ?

should we define a viscoelastic test data also?

can you please tell me what rubber material you are using.

Is it possible for u to upload video regarding viscoelastic material constants evaluation from test data?

Hi, thanks for such a good video. Anyways, I have 2 questions. (1). why the Ogden constants that you generated are different from those provided in the paper? (2). can we use the Ogden constants which we generated in Abaqus for material input in LS-Dyna simulation? I noticed that even we use the same nominal tensile stress strain of the material and generate the material constants, those constant generated from Abaqus are different from those generated from LS-DYNA. Anyone please correct or give me some ideas on this. Thank you in advance.

Great! it's very helpful, Just a question: Should the strain data be percentage values ?

Here you have used test data .. what if we dont have test data and use hyper elastic material with coefficients only .. how to derive the equation U... What is I1 and I2?

Sir, how to find Johnson cook material model using test data

thanks

please share the excel sheets, thanks
