Plots of the tangent modulus of elasticity for a variety of materials are available in standard references.
2.
The tangent modulus quantifies the " softening " of material that generally occurs when it begins to yield.
3.
In solid mechanics, the slope of the stress strain curve at any point is called the tangent modulus.
4.
The tangent modulus is useful in describing the behavior of materials that have been stressed beyond the elastic region.
5.
For example, a structural analyst may use the tangent modulus to quantify the buckling failure of columns and flat plates.
6.
A more accurate approximation of the buckling load can be had by the use of the tangent modulus of elasticity, E t, which is less than the elastic modulus, in place of the elastic modulus of elasticity.
7.
?-Helices under axial tensile deformation, a characteristic loading condition that appears in many alpha-helix-rich filaments and tissues, results in a characteristic three-phase behavior of stiff-soft-stiff tangent modulus.
8.
The tangent modulus is a line drawn tangent to the stress-strain curve at a particular value of strain ( in the elastic section of the stress-strain curve, the tangent modulus is equal to the elastic modulus ).
9.
The tangent modulus is a line drawn tangent to the stress-strain curve at a particular value of strain ( in the elastic section of the stress-strain curve, the tangent modulus is equal to the elastic modulus ).
10.
Since at this stress the slope of the material's stress-strain curve, " E " " t " ( called the tangent modulus ), is smaller than that below the proportional limit, the critical load at inelastic buckling is reduced.
