Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. The specific modulus is often important in aerospace applications in which maximum strength for minimum weight is required.

The dimensional analysis yields units of distance squared per time squared.

The structural members of the Crew Exploration Vehicle have been specified to be an aluminum-lithium alloy for this property, among others.
