Stress, strain, and NMR

Solid State Nuclear Magnetic Resonance, 2006
Experimental and ab initio results that demonstrate the effect of stress on the nuclear magnetic resonance spectra of materials are shown. The design of a cell that generates uniaxial compressive stress is presented, and results on gallium phosphide and lead nitrate single crystals that illustrate the observable results of the stress are shown.

Stress–Strain Relations

2021
In the previous chapters, the state of stress at a point was defined in terms of six components of stress, and in addition, three equilibrium equations were developed to relate the internal stresses and the applied forces. These relationships were independent of the deformations (strains) and the material behaviour.

The stress-strain relationship for the skin

Journal of Biomechanics, 1976
Abstract The skin is an inelastic material. But in cyclic loading and unloading the stress-strain loop is unique after preconditioning, and is insensitive to strain rate. We define a pseudo strain potential for such a material so that the stresses can be derived from the expression S ij = ∂(ϱ 0 W) ∂e ij , where W is the ...

On the stress-strain relation for skin

Journal of Biomechanics, 1979
Abstract A simple model of the collagen fiber network in the dermis is used to calculate the strain level at which the stiffness of skin abruptly increases. The calculated critical strain level (57%) agrees roughly with experimental values. It is suggested that entry into the high-modulus region of the stress-strain curve of skin is simply a ...

Stress-Strain Analysis And Stress-Strain Relations

1992
Abstract The material in Chapter 2 should be familiar from courses in mechanics of materials and design, and so serves as a review. The notation and sign convention for both stress and strain follow that generally given in the theory of elasticity.

Stress, Strain, and Mechanotransduction in Cells

Journal of Biomechanical Engineering, 2001
It is widely accepted that numerous cell types respond to mechanical stimuli, yet there is no general agreement as to whether particular cells respond directly to stress, strain, strain-rate, strain-energy, or other mechanical quantities. By recalling the definitions of the mathematical (not physical) concepts of stress and strain, it is suggested ...
