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. The SI unit for specific strength is Pa ...
Specific modulus: Modulus per unit volume (MPa/m^3) Specific strength: Strength per unit density (Nm/kg) Specific weight: Weight per unit volume (N/m^3) Surface roughness: The deviations in the direction of the normal vector of a real surface from its ideal form; Tensile strength: Maximum tensile stress of a material can withstand before ...
Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. 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.
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.
Plot of Young's modulus vs density. The colors represent families of materials. An Ashby plot, named for Michael Ashby of Cambridge University, is a scatter plot which displays two or more properties of many materials or classes of materials. [5] These plots are useful to compare the ratio between different properties.
A United States Navy Aviation boatswain's mate tests the specific gravity of JP-5 fuel. Relative density, also called specific gravity, [1] [2] is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
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 carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm 3, its specific strength of up to 48,000 kN·m·kg −1 is the best of known materials, compared to high-carbon steel's 154 kN·m·kg −1. Under excessive tensile strain, the tubes will undergo plastic deformation, which means the deformation is permanent. This ...
