  Title Shear modulus of an elastic solid under external pressure as a function of temperature: The case of helium Type
  Year 2012 Publication Physical Review B Abbreviated Journal Phys. Rev. B  
  Volume 85 Issue 6 Pages 6 pp  
  Keywords  
  Abstract The energy of a dislocation loop in a continuum elastic solid under pressure is considered within the framework of classical mechanics. For a circular loop, this is a function with a maximum at pressures that are well within reach of experimental conditions for solid helium, suggesting, in this case, that dislocation loops can be generated by a pressure-assisted thermally activated process. It is also pointed out that pinned dislocation segments can alter the shear response of solid helium by an amount consistent with current measurements, without any unpinning.
