  • ElAM: A computer program for the analysis and representation of anisotropic elastic properties 

    Marmier, Arnaud; Lethbridge, Zoe A. D.; Walton, Richard I.; Smith, Christopher W.; Parker, Stephen C.; Evans, Kenneth E. (Elsevier, 2010)
    The continuum theory of elasticity has been used for more than a century and has applications in many fields of science and engineering. It is very robust, well understood and mathematically elegant. In the isotropic case ...
  • Version 4.0 

    Marmier, Arnaud (2009-08-19)
    The continuum theory of elasticity has been used for more than a century and has applications in many fields of science and engineering. It is very robust, well understood and mathematically elegant. In the isotropic case ...
  • Elastic anisotropy and extreme Poisson's ratios in single crystals 

    Lethbridge, Zoe A. D.; Walton, Richard I.; Marmier, Arnaud; Smith, Christopher W.; Evans, Kenneth E. (Elsevier, 2010)
    The relationship between elastic anisotropy and extreme Poisson’s ratio behaviour (either positive or negative) in single-crystalline materials has been investigated using experimentally determined single-crystal elastic ...
  • Modelling negative linear compressibility in tetragonal beam structures 

    Barnes, D.L.; Miller, W.; Evans, Kenneth E.; Marmier, Arnaud (Elsevier, 2012)
    Most materials compress axially in all directions when loaded hydrostatically. Contrary to this, some materials have been discovered that exhibit negative linear compressibility and, as such, expand along a specific axis ...
  • Negative compressibility in platinum sulfide using density-functional theory 

    Marmier, Arnaud; Ntoahae, Petros S.; Ngoepe, Phuti E.; Pettifor, David G.; Parker, Stephen C. (American Physical Society, 2010)
    The structural and dynamic properties of the mineral Cooperite (PtS) are investigated using density-functional theory. The results show that a competition with the less symmetric but more compact PdS structure leads to a ...
  • Phase-change technologies: from PCRAM to probe-storage to processors 

    Wright, C. David; Ashawaraya, S.; Ashwin, Peter; Aziz, Mustafa M.; Hicken, R.J.; Kohary, Krisztian; Liu, Y.; Marmier, Arnaud; Shah, P.; Vazquez Diosdado, Jorge A.; Wang, Lei (2010)
    Phase-change materials based on chalcogenide alloys, for example GeSbTe and AgInSbTe, show remarkable properties such as: the ability to be crystallized by pulses in the (hundreds of) femtoseconds region while at the same ...
