Composite density by rule of mixtures

Calculates a simplified composite modulus from fiber volume fraction and fiber and matrix moduli.

Calculates helper laminate thickness from user-provided ply count and single-ply thickness.

Calculates fiber and matrix volumes, masses, theoretical density, and mass fractions from total volume and fiber volume fraction.

Estimates the volume fraction of an identifiable phase from the phase point count and total grid point count.

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

Calculates aluminum mass from volume and user-provided density; it does not use an alloy database.
