16.9. Linear Elastic

BEGIN PARAMETERS FOR MODEL LINEAR_ELASTIC
  YOUNGS MODULUS = <real>
  POISSONS RATIO = <real>
  SHEAR MODULUS  = <real>
  BULK MODULUS   = <real>
  LAMBDA         = <real>
END [PARAMETERS FOR MODEL LINEAR_ELASTIC]

The LINEAR_ELASTIC material is used for modeling infinitesimal strain elastic response. Generally this model is used for code verification work when comparing to infinitesimal strain solutions. This differs slightly from the standard ELASTIC model which is formulated for general finite strain.
