Material stiffness cost index

Calculates a notional comparative strength index relative to density and cost per mass.

Calculates cost per unit volume from user-provided cost per mass and density.

Calculates a simple score as property value divided by density.

Calculates a notional weighted score from three user-provided scores and weights.

Calculates a notional comparative thermal shock resistance index; it is not a criterion from a specific standard.

Calculates plane-wave characteristic acoustic impedance Z = rho*c.
