I'm interested in the example of shaped charge (RPG) simulation on Page 45 of this PPT presentation: https://ftp.lstc.com/anonymous/outgoing/support/PRESENTATIONS/blast_slavik_ucsd.pdf

The last page shows the author's contact info and the link to download the example files. However, both have expired. 

I'd appreciate it if anybody could let me know how to find these files, or share with me these files or similar examples. If anybody has the current contact info of this author (Todd Slavik), please also share.

Thank you for your attention!

The examples cited at the end of this file are NOT for the shaped charge simulation, but rather the “Building” example starting on Page 15 and what I believe are three models of the bast loaded plate shown on Page 42.

 

The shaped charge (RPG) illustration is not an available example but rather an illustration of a possible application of Load Blast Enhanced with option BLAST=3.

 

Shaped charges cannot be modeled using Load Blast Enhanced. Use of Multi-Material ALE is required. Examples may exist in the papers available on this site: https://www.dynalook.com/

Dear Len,

Page 40 of the presentation mentions visualizing the incident wave in air using a slice of shell elements. Is there any further details or examples on how to do this?

Regards,
Ameen

If you define a plane of shell elements passing through the Load Blast Enhanced bomb center and define them as participating in the blast loading, i.e. via *LOAD_BLAST_SEGMENT, then the blast pressure on those segment can be visualized using LS-PrePost.

 

Indeed, any shell element segments thus defined will display blast pressure fringes using LS-PrePost.                           --len

I have figured out how to simulate these two scenarios. Thank you.
