Blast only damage

[Desert Mariner]

Does anyone know what formula is used to determine explosive blast damage? I’m working on specs for the SOHG (Scalable Offensive Hand Grenade) as a replacement for the MK3A2 but haven’t found the formula anywhere.

For those unfamiliar with the SOHG, its like grenades crossed with Legos. The user can “stack” up to three at a time to adjust the level of blast and destruction. One article on the munition puts it better than I could…“To visualize what this hand grenade offers, think about a small wooden shed that you’d buy at Home Depot. If you use just one module, you’ll blow the door open and the windows out. Select two modules and you’ll knock the shed off its foundation. But screw on all three sections and the real magic happens; you’ll transform the shed into splinters.”

It's plastic case is 53mm in diameter and comes in two sizes 85mm and 135mm, containing 115g and 225g of Comp B (Heksotol 60/40) respectively.
