ELASTIC constants of crystals may be determined from measurements of diffuse X-ray reflexions given by them. According to the theory of Waller 1, diffuse reflexions are produced as a result of the ...

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 ...

Subjecting a material to a hydrostatic stress also causes elastic deformation. The stress is the pressure, p, acting on the body and the strain, d = DV/V. These quantities are related through a ...
