I have multiple small diameter solid particles hitting the human body or human skin. Can i find penetration depth of these particles with this software?
Thank you very much for the feedback. Assumed velocity is (-900 m/s) but actual velocity of the bullet is in the range (818.11 m/s and 954.46 m/s) as can be seen in the bullet colour. 1232.2 m/s is maximum velocity value in the plot not the actual velocity of the bullet.
What is the difference between explicit dynamic module and autodyn module available in ansys workbench? Can I do impact analysis on composite material using explicit dynamic module which has been done in autodyn by researchers?

@@riccardop2219 in explicit dynamic you can perform shell models only not solid Atlast the answer you will get is same only. Advantage of using shell over solid is that it will save your simulation time and cost.
Thank you very much for the feedback. Ofcourse, I would love to share those files but I don't have a website for that purpose right now. I can send them to you through e-mail.
Hello. Does it make a big difference if you define the body interaction with friction? In your example may be not, but with a bigger plate which would stops the bullet?
If you are working on problems involving Finite Element Analysis (FEA) please use the link below. There are answers to similar problem on how to find energy absorption in ANSYS Workbench Explicit Dynamics. www.researchgate.net/post/How-i-can-find-energy-absorption-in-ls-dyna-explicit-dynamics For residual velocity calculation there are many references and TH-cam videos online. Good luck!
Could you please send the file with the geometry to it. I just don't understand how to make a bullet at a distance from the plate. I wrote to you on Instagram about three weeks ago. Please answer, thank you!

DYNAMIC ANALYSIS OF LAMINATED.pdf Go through the materials thoroughly. You can also watch my video and follow every step accordingly to apply the velocity vector in the correct direction(depending on your chosen coordinate system during modeling). If you still encounter the same problem then send me a screenshot of your bullet and direction of velocity application including velocity value. I await feedback. Good luck!
@@edidiongumana-cadcamcaebureau hello I have obtained the plot of velocity vs time but the velocity plot is showing constant throughout time it should have varied any suggestions?
@user-zc6eg2es9t The time taken to run ANSYS Fluent calculation depend on factors such as Mesh Optimization. However, ANSYS calculation should be done on a different (faster) hard drive. It is possible to find the actual time taken for the simulation and also the average time taken per iteration. Just type "parallel>timer>usage" in the console. You will get what you need. It works only on parallel processing. Also, if it is a transient calculation, you can see the flow time in the Console.
Thanks for the Video. I have learnt a much out of it

very nice but how to greater than total velocity before assumption velocity (-900 m/s) your assumption but total velocity is 1232.2 m/s?

HOW CAN I GET THE BULLET DIMENSIONS AND BULLET PROF JACKET DIMENSIONS ..... PLZ REPLy .....
Reply sir... Plz
@cs-qk9yw, the dimensions of both the bullet and the impact surface including the thickness depend on you.
Sir this is my final year project plz reply

Hello @barbazote4728! If the target body is a multi-layered fabrics the friction effect will be noticed during bullet impact.

how much time did it took to solve, and how many nodes and elements where there.
@user-zc6eg2es9t The time taken to run ANSYS Fluent calculation depend on factors such as Mesh Optimization. However, ANSYS calculation should be done on a different (faster) hard drive.
It is possible to find the actual time taken for the simulation and also the average time taken per iteration.

When I tried it, the element did not break. What's the trick?
Hello Tao, check your vector direction and follow every step as shown in the video. Good luck!
Hi, did you find the solution? I have the same problem bullet hits the plate but doesn't break it.
just talk doesn't hurt
