Αxial stiffness for an element in tension

Description

The stiffness of a body is a measure of the resistance offered by an elastic body to deformation.
Tension describes the pulling force exerted by each end of a string, cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member, or similar three dimensional object.
Stiffness for an element in tension is depended on the material and the shape of the element and boundary conditions.
