resiliency
    n 1: an occurrence of rebounding or springing back [syn:
         {resilience}, {resiliency}]
    2: the physical property of a material that can return to its
       original shape or position after deformation that does not
       exceed its elastic limit [syn: {resilience}, {resiliency}]
    

resilience \re*sil"i*ence\ (r[-e]*z[i^]l"[i^]*ens), resiliency

   2. The power or inherent property of returning to the form
      from which a substance is bent, stretched, compressed, or
      twisted; elasticity[1]; springiness; -- of objects and

   4. (Mech. & Engin.) The mechanical work required to strain an
      elastic body, as a deflected beam, stretched spring, etc.,
      to the elastic limit; also, the work performed by the body
      in recovering from such strain.
