Premise[]
Did this a while back off-site, someone asked me to redo it here. Basically, this applies whenever a character says "eyyy lmao ur door is broke" and destroys a relatively normal door. Note that in certain circumstances, another calc should be done- if the door is clearly much larger then this is inaccurate, this works for doors of relatively standard size.
Calc[]
Standard size for a door is 203.2 cm tall, 91.44 cm wide, and 3.334 cm thick.
Volume = 61947.75 cm^3
Fragmentation values of some materials. Using average Pulv for wood and steel since they both have a low- and high-end.
Wood Door[]
Fragmentation = 516644.24 Joules
V. Frag = 1136121.74 Joules
Pulverization = 2907827.38 Joules
Steel Door[]
Fragmentation = 1.289e7 Joules
V. Frag = 3.522e7 Joules
Pulverization = 4.058e7 Joules
So there you have it. This would account for relatively uniform shape door busting. Old house doors would probably yield more but not significantly so.
