Blast room spreadsheet 1

[WARose]

Does anybody have a blast room spreadsheet? I was looking for one where you can input a TNT equivalence and get wall pressures for a internal explosion. (Especially if venting on one side is provided.)

Thanks in advance.

I have a spreadsheet that gives you Pr, Po etc for a given R and W if that helps. Basically just the Kingery Bulmash curves digitized.

Anything like that would help. Thanks bones.

Let me know if you have any issues with the attached spreadsheet. It was part of a sprawling blast design excel VBA project that I haven't really touched since 2015. I've stripped all the VBA out and just left the bits for calculating blast load parameters.

I believe I originally digitized the blast load curves using another piece of software that allowed me to manually create data points from the Kingery Bulmash plot files provided with the UFC manuals. I did a cursory review and the data still looks good, but it's been 7 years since I've done a deep dive.

All a long way of saying please use with caution.

Thanks again bones.

Of course. Glad to be of help.
