The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

Most models of DNA elasticity ignore the details of how it bends on short length scales. Now, high-resolution atomic force microscope images of DNA on a surface suggest that it is much more flexible ...

When a material experiences an applied uniaxial tensile stress, s, it displays a strain response, e. In the initial stage of strain, the response is linear in the stress and may be described by ...
