0011658: Bronze, steel and bone have incorrect material value placeholders
One can calculate bulk modulus, shear modulus and young's modulus from any of the other two, or from any of those plus poisson's ratio. As such, we can calculate bronze, steel and bone's placeholder values.

Bronze:

[COMPRESSIVE_STRAIN_AT_YIELD:899] 67
[SHEAR_STRAIN_AT_YIELD:384] 44.8

Steel:

[SHEAR_STRAIN_AT_YIELD:538] 80

Bone:

[COMPRESSIVE_STRAIN_AT_YIELD:3846] bulk modulus 26 GPa
[TENSILE_STRAIN_AT_YIELD:53] young's modulus 66 GPa
[SHEAR_STRAIN_AT_YIELD:114] shear modulus 30.7 GPa
