Simulation of Ball Impact on plate (Perforation) using ABAQUS tutorial

Here I have used Abaqus Explicit analysis for perforation and element deletion has been used

Interesting tutorial. That I actually wrote a few years back. Amazing how widely used they are!!

i am modelling low velocity impact on composite plate with 8 layers. To reduce the simulation time I am considering q quarter model with two symmetry boundary conditions in x and y directional and fixed in other side. I am using a rigid impactor with some mass and velocity, my doubt is should I consider total mass of the impactor or 1/4 th mass of the impactor since i am taking only 1/4th model of composite plate.

Hey, I am working on a similar project. Could you let me know if your simulation works??? You are using VUMAT subroutine or explicit modelling with surface-to-surface contact?

@@rizwanmohnavi hii.. my simulation works with quarter model with 1/4th mass. i am using VUMAT...are you using VUMAT?

In the perforation2 job you had given 40 m/s velocity to the ball and the total run time is 0.001. I gave the similar values and perforation could not happen. Then you immediately switched to the original perforation job which shows perforation of the shell plate. I tried with 150 m/s and finally, I got the perforation. How did you get the results and perforation with just 40 m/s velocity. Please explain. I would like to thank you for showing this wonder simulation. Can you perform the similar simulation on a solid plate of 15 mm thickness with the multiple impacts of 10 balls at the same spot?

YES EXACTLY, MAY WE HAVE THE ORGINAL FILE THAT YOU USED?

Same.

Yo, year later, I have the same problem lol. Have you managed to solve it?
