A SURPRISINGLY simple FEA method to determine BULK MODULUS

This video shows a surprisingly simple finite element based approach of determining the Bulk Modulus of a homogeneous block of Polypropylene. Here, the theory behind numerical model setup was explained, the model set and ran, and bulk modulus determined. To prove it works, I determined analytically the bulk modulus and this was found to agree with the numerically determined bulk modulus. This approach will be useful for analysis of bulk modulus of heterogeneous media like lattice and syntactic foam structures.

Thanks so much for this video mentor.

[@MichaelOkereke]

You are very welcome

[@ManishSingh-gc5fv]

Thanks, Dr. Michael for making and uploading the video. I had requested this to you last week.💛💛Again I request you to make video on bulk modulus of any lattice structure. Again Thanks in advance.💚💚

[@MichaelOkereke]

Thanks @ManishSing for the comment. I have now published a video for lattice structures and bulk modulus which you can access here: kzbin.info/www/bejne/qWfGiKKipNt7pMUsi=JI21au2I1FYPVZGa Hope this helps!

Dear Sir, Can you make a video for compression simulation of a composite metal system in which: 1) There is a Ti6Al4V lattice structure (3d printed) (imported to Abaqus from solid-works) 2) Molten Zinc was poured in that lattice and hence Zn is embedded everywhere in the lattice. Then extracting stress-strain curve from the simulation result (with help of history output) The plastic properties are needed as well (power law parameters for Ti6AL4V and Zinc from literatures) Note: Please share your purchasable content which is/are related to this simulation. Regards.

This seem like a large project and I do not take up complete projects. I only make videos to show specific elements to support students. This seem like something you can actualy research for yourself. If you look at the description sections of my videos, you will see resources I have to support your computational journey... mainly in form of software... which you can also get here: www.cmvideos.org/shop/

[@NAVDEEPMALIK-ve3sr]

Hi sir, could you make video on elastic young's modulus under tensile loading for cellular honeycomb or reentrant (specifically) structures

[@NAVDEEPMALIK-ve3sr]

i could provide analytical values to you for validation
