|Summary||0000639: Some impact elasticity values are clearly wrong|
|Description||Impact Elasticity for some metals in DF:|
I'm assuming that high elasticity => deforms more under a given stress, as per real world definition (Strain = E * stress).
While I can't find impact elasticity for real world data, Young's Modulus (inverse tensile elasticity) of gold and silver are virtually identical. Given their similar behavior under many other circumstances based on their periodic table placement and properties, I would assume this holds true for all types of elasticity.
Its certainly the case that gold should not be stiffer than iron and steel.
In fact, it should probably be steel < iron << gold ~= silver, which means one of iron or steel is also wrong. My best guess is that steel should be stiffer than bronze as well, and so steel should have an impact elasticity <600.
(I've mostly looked at weapon-capable metals and impact elasticity, so there may be other inappropriate values)
|Steps To Reproduce||Its an incorrect data entry in the raws|
