The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength.
It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required. The dimensional analysis yields units of distance squared per time squared.
The composite has a considerably higher shear stiffness to weight ratio than an equivalent beam made of only the core material or the facesheet material. The composite also has a high tensile strength to weight ratio. The high stiffness of the facesheet leads to a high bending stiffness to weight ratio for the composite.

Strength/weight ratio – Construction materials are commonly categorized by their strength to weight ratio—or specific strength, which is the strength of a material divided by its density. These ratios indicate how useful the material is for its weight, which in turn indicates its cost and ease of construction.
Since steel has a specific gravity of roughly 7.8, these materials have a strength-to-weight ratios eight times that of high-strength steels. Strength-to-weight ratios for UHMWPE are about 40% higher than for aramid. The high qualities of UHMWPE filament were discovered by Albert Pennings in 1968, but commercially viable products were made ...

Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
