Elastic Materials

Definition

Isotropic, linear elastic material with losses.

Description

Mechanical
E' Young's Modulus Pa or N/m2
NU' Poisson's Ratio  
  Density kg/m3
Losses
E" Imaginary part of the Young's Modulus
NU" Imaginary part of Poisson's ratio
Must verify E" ≥ 0
and -E"(1+NU')/E" ≤ NU" ≤ E"(0.5-NU')/E'
Magnetic
Relative magnetic permeability
Superpose magnetic domain to elastic domain

Illustration

ATILA Implementation

When the magnetic permeability is enabled, the mesh is "duplicated" so that a magnetic field computations can be performed on top of the elastic domain. Thus, both domains share the same nodes. This feature is typically used in magnetostrictive problems.
